A Comparative Structural, Architectural and Cost-Based Analysis of Seismic Design Principles Applied In Reinforced Concrete Residential Buildings In Turkey
(CRC Press-Taylor & Francis Group, 2010) Özmen, Cengiz; 56939
This study demonstrates that it is possible to design earthquake resistant reinforced concrete residential structures without significant compromises in the spatial quality and economic viability of the building. The study addresses architects, structural engineers and private entrepreneurs who are the important players in the Turkish construction industry. In structural analyses, a set of four parametric mathematical models are used to demonstrate the effects of increased column cross-sections and use of shear-walls on the seismic performance of reinforced concrete structures. Architectural analyses are carried-out through three case-studies selected from the earthquake affected city of Bolu in Turkey. Cost-based analyses demonstrated that it is possible to design earthquake resistant reinforced concrete residential buildings with a 4-6% increase in the building cost and an economically acceptable 10% decrease in profits.
A neo-structuralist perspective on architectural theory of post-truth era: Re-constructing the architect-subject
(2022) Cavdar, Rabia Cigdem; 237969
The fundamental aim of the article is to scrutinise the transformations and yet pseudo-disappearance of architectural theory with an archi-theoretical gaze. It is an attempt to reread/ write the architectural theory of the 21st century in the shade of the claim that architectural theory was dead. It is obvious that not only in architecture but also in all social-life structures, free-floating meanings began to invade the totality; every concept that constitutes societal life was dislocated after the digital turn. Concepts began to be depicted with the prefix 'pose; such as post-historical, post-humanist, post-political, post-ideological, post-theory, and even, 'post-truth'. Under these circumstances, the main argument of the article is that architecture could be run as a 'point de capitone' -in Lacanian terminology-, between the subject -described as the sublime object of ideology by Zizek- and the ideology; the role of architecture is to work as a stabiliser on/between the liquid surfaces/grounds. In the context of the main argument, the article is structured on three conceptual domains, which are that ideology, subject and architecture. Architecture as a point de capitone has a significant role in the reconstitution of incommensurable dialectic in the 'redoubling procedure; which works for both recreating the lost otherness, and providing social antagonism.

A novel approach for renovation of current social housing stock based on energy consumption in Turkey: significance of occupant behaviour
(2019) Harputlugil, Timuçin; Harputlugil, Timuçin; Pedergnana, Matthieu; Sarıoğlu, Esra; 26110; 40295
The goal of this research is to attempt establishing occupant behaviour profiles and how that behaviour impacts energy consumption with regard to indoor comfort levels in the current social housing stock in Turkey. The data consists of a large statistical survey that included four housing complexes situated in different climate regions in Turkey. Another more detailed survey was given to occupants of housing blocks in Ankara. Apartments were also monitored during a one-week period in summer and again in winter. All collected data were evaluated by sensitivity analysis. The results showed that occupant presence at home and operating windows had the most profound effect on internal loads and comfort levels whole year. Additionally, the transparency level of curtains, impacts the indoor temperature during the winter time. The results were used to develop a web-based tool which is going to be a guide for renovation strategies of current housing stock.
A research on comparison of elevator traffic analysis methods in educational buildings
(2023) Harputlugil, Timuçin; Harputlugil, Timuçin; 40295
Purpose: Regarding elevator design in educational buildings; It is aimed to investigate the legal framework, to integrate dynamic simulation programs to design process, to compare traditional and dynamic simulation methods, to evaluate the adequacy of elevator features specified in the legislation and to determine the optimum scenarios according to the minimum requirements.Theory and Methods: Based on the findings of the literature review, which examines the issue of elevator traffic analysis together with the legislation and regulations, the carrying capacities of the elevators in the educational buildings designed by the Ministry of National Education (MNE) are tested. The stability of the system is tested by analyzing the conditions where only the disabled, disabled and building workers can be used together and all building users can use the elevators with the dynamic simulation method (with Elevate Software). The limits of the system are determined based on the waiting times during the peak usage periods. The findings of the study are evaluated according to the waiting times determined by CIBSE Guide D and the Chamber of Mechanical Engineers followed by the discussion of the outcomes.Results: The issue of elevator design has been overlooked in educational buildings, and a comprehensive elevator traffic analysis method has not been defined. For the effective use of all occupants, elevator design should be handled comprehensively with considering potentials of dynamic simulation method.Conclusion: According to the findings of the study, it is noted that the number and capacity of elevators in the legislation for educational buildings are determined only for minimum conditions and for disabled users. In addition, the legislation (considering calculation methodology) is not specific for educational buildings but related with buildings in general with public use. Considering the occupants, and their profiles of the educational buildings, a more comprehensive traffic analysis with the dynamic simulation method may enable the elevators to be designed and to be used more efficiently.
A research on occupant behaviour pattern of dwellings in the context of environmental comfort and energy saving
(Gazi Univ, Fac Engineering Architecture, 2016) Harputlugil, Timuçin; Harputlugil, Timuçin; 40295; 36110
Occupants make a passive contribution to the building energy balance by their very presence; they also can have an active role through activities like opening windows, changing thermostat set points, tuning radiator switches or lighting switches, etc. Furthermore, in existing buildings, occupants also play a role in decisions regarding any interventions in the fabric and systems, especially where occupants own the building. In this paper, an evaluation of the survey results applied to occupants of dwellings in order to reveal effects of occupant behavior on energy consumption. The survey was applied to occupants of dwellings presented in four different climatic zones. There are two main issues aimed in the survey. Firstly, it is aimed to find out behavior patterns which are mostly effective on energy consumption. The other aim is to query the perception of occupants on comfort conditions and energy saving potential. The results of the survey showed that dominant occupant behavior which have an effect on energy consumption very significantly is opening/closing window. A major amount of occupant is aware of saving electricity; thus %92.9 of occupants prefer energy saving lamps for artificial lighting. Another essential result of survey is, in a general manner, sensitivity on energy consumption and satisfaction of comfort are increasing by education level increases.
A Simple Selection Method of PV Systems for University Campuses
(2023) Bara, Mariam; Ulukavak Harputlugil, Gülsu; 36110
This paper briefly outlines part of the research work being carried out on the application of the photovoltaic systems to cover universities’ electrical energy needs, with due consideration to the technical, architectural, economic, social. and legal aspects and impacts of this application. The paper considers optimizing the PV system selection objectives and methodology with a case study application. at a university campus in Ankara, Turkey. The main objective here is to develop a practical simple method of selecting an optimum PV system that gives the maximum energy yield possible in a certain period of one year, with the minimum specific energy cost per kWh, where a multiple-variable multi-criteria decision-making making method is applied, to help designers and system engineers in selecting the optimum system. The developed method is demonstrated in the example of the typical case, where the recommended PV system was turned out to be at an Azmuth angle of 0 degrees, the PV technology was monocrystelline Silicon, the annual electrical energy yield per 100 m2 of PV modules surface area 22.4 MWH/Year, the specific electrical energy cost was 0.15 Euos/Kwh, as a first merit option, making a difference of around 13% of saving compared with the 10th last option. The work concludes that a viable PV application is feasible, encouraging its application in various campuses provided that comprehensive planning and careful considerations are given to the related aspects.
Aciksaray "Open Palace": A Byzantine Rock-Cut Settlement in Cappadocia
(Walter De Gruyter GMBH, 2014) Öztürk, Fatma Gül; 140902
Courtyard complexes formed entirely out of the volcanic rock mass in Cappadocia, in Central Anatolia, differ from the other rock-cut structures in the region, in both scale and elaboration of design. There are more than forty such complexes in Cappadocia, either gathered in one location or isolated. Located on the Nevsehir-Gulsehir road, Aciksaray contains nine such complexes in close proximity, many of which feature monumental facades as well as reception areas and utilitarian spaces such as large stables around a courtyard. This paper, in the light of survey results, presents site analysis and architectural readings that lead the discussion of the nature and stages of occupation at Aciksaray. By doing this, the paper aims to bring new insights to the discussion on courtyard complexes, adding details and nuance to our understanding of the Aciksaray settlement, while noting similarities with other settlements in the region. Underlining the secular and elite character of the Aciksaray settlement, this study contributes in particular to enlarging the picture of medieval life in Cappadocia, and in general to the studies of Byzantine domestic architecture, for which architectural evidence is still scarce.
Addressing Earthquake Risk and Climate Crisis together in Spatial Planning
(2021) Orhan, Ezgi; Orhan, Ezgi; 34038
Cities' vulnerability to natural and man-made threats are ever increasing. Cities are under the threat of both natural disasters such as earthquakes, avalanches and landslides; and climate-driven challenges such as excessive precipitation, heatwaves and droughts. This calls for a need of handling natural and human systems together for the future of cities. However, climate and earthquake action plans which naturally present a direct link to spatial planning, are often produced separately in the Turkish planning practice. This study advocates that strategies for combating earthquake and climatic challenges should be harmonized together within the spatial planning system, and respectively, aims at presenting a holistic planning approach. For this purpose, the study first examines the ways in which disaster and climate issues are addressed in the current laws and national action plans. Then, in line with the 'Regulation on the Preparation of Spatial Plans', it examines the spatial planning scales with an aim of determining the potential areas in which disaster and climate issues could be planned together. Taking this as a point of departure, the paper presents a set of planning strategies responding to earthquake risk and climate crisis at regional, city, neighbourhood and building scales. It discusses synergies and conflicts among these strategies at different scales. This study targets to develop a holistic perspective for earthquake and climate change induced disasters, for the decision-makers and practitioners operating in spatial planning processes.

Aesthetic Assessment of Kitsch: A Reading on Bad Taste in Kant’s “Critique of Aesthetic Judgment
(2023) Uysal Ürey, Zeynep Çiğdem; 18663
Kitsch, devised as a term of modern aesthetics after the 19th century, indicates an aesthetic value judgment that is identified as ‘bad taste’. It is acknowledged that the issues of aesthetic judgment and taste were systematically addressed for the first time by Immanuel Kant in his “Critique of Aesthetic Judgment” in the 18th century. This study attempts to reevaluate the notion of kitsch as an aesthetic value judgment through a reading of Kant’s arguments over the concepts of aesthetic judgment, taste, and bad taste as presented in his work “Critique of Aesthetic Judgment”. Tracing the notion of kitsch as bad taste in the writings of Kant would demonstrate possible convergences or discrepancies there may be and would be significant for providing an understanding about the philosophical roots of the term. With such an attempt, this study conducts a discursive analysis, and respectively examines the notion of kitsch as an aesthetic judgment of taste; the notions of aesthetic judgment and taste in Kant’s “Critique of Aesthetic Judgment”; and the notion of ‘bad taste’ thereof in order to make a comparison with the notion of kitsch. The examination that looks for the definition of bad taste in the “Critique of Aesthetic Judgment” reveals that the conditions of ‘bad taste’, as portrayed by Kant through the role of charm and emotion in aesthetic judgment, overlap with the characteristics of kitsch on the basis of sentimentality and desire for attention. Consequently, as a result of the reading on bad taste in Kant’s arguments, this study argues that over the traits of sentimentality or the pretentious use of charms and emotions, the philosophical roots of the term kitsch as an aesthetic value judgment existed long before its name has been coined.
Affiliation of Archaeological Sites and People:Case Studies on Interpretation and Presentation Approaches
(Cankaya University Press, 2018) Kalfa Ataklı, Başak; 257609
Archaeological heritage sites are one of the most trustworthy sources of our cultural and sociological history. Thus, once the archaeological heritage comes to daylight after centuries of darkness, they would like to connect with people immediately to pass the information they have been carrying. Hence, the bonding needs a catalyst in order to reflect the spirit of the place. This catalyst is called “interpretation and presentation”. Many approaches from excavating and presenting to virtual off-site tours have been used from the first archaeological excavation to now. These methods go beyond the physical representation of the site solely but help its audience to comprehend its spirit. In this study, three archaeological sites from different countries are investigated in terms of their interpretation and presentation methods. These sites are Colonia UlpiaTraiana (Archaeological Park Xanten) in Germany, Ostia Antica in Italy and Çatalhöyük in Turkey. Having both distinct and common methods, these three sites provide an understanding how interpretation and presentation approaches place themselves as a communication tool between people and the archaeological site.

An Architectural Reading of Zamyatin’s Intersectional Elements in The Novel “We”
(2021) Çavdar, Rabia Çiğdem; 237969
“We” was written by Russian novelist Yevgeny Zamyatin in 1921 after the Soviet Revolution. To be at the edge of the conflicts was scrutinized at the novel, in which the protagonist, labeled as D-503, having a tentative position at the well-defined ground by the power which presented itself as the truth or the law. The narration was constructed via the diary of protagonist; how D-503 perceived the paradigm, which he had lived in, what kind of conflicts and contradictions he had been living with the system was questioned. Zamyatin chose very specific architectural elements to explain and criticize the dominant paradigm of the era -early 1920’s, and the periphery of that dominancy; like Green Wall, Glass Wall, logical labyrinth, cube square, and etc. These intersectional elements were constructed as in the form of blurred voids in order to unfold the ideological positions of the written period of the novel. The materialization and meaning of the walls, could be read as dialectic conceiving of how Zamyatin scrutinized both the revolution and the paradigm. As being a dystopia, the novel “We” criticizes the idealized beliefs that were presented as transparent, lucid and conductive.

An investigation on indoor soundscape in high school environment
(Cankaya University Press, 2018) Çankaya Topak, Sıla; 272044
This study presents an evaluation of the students’ preferences and acoustic comfort perception to understand the indoor soundscape in a computer laboratory, Ankara, Turkey. To understand the existing acoustical conditions, sound level (LAeq) was measured. In subjective survey, 43 students participated an acoustic comfort and sound preference questionnaire. Results showed that motorized transport sound sources are perceived as annoying sound sources whilst human-based sound sources are evaluated as relaxing sound sources. Although sound levels were measured higher than recommended, students evaluated sound levels as both high and low. Therefore, it is found that soundscape cannot be evaluated by only physical indicators as sound levels, it should cover the information about the context which sound is heard.
An investigation on The Effect of Drawing Techniques towards Students’ Performance and Perception in Architectural Education.
(2018) Harputlugil, Timuçin; Çankaya Topak, Sıla; Özkan Öztürk, Nur; 40295; 272044; 257557
Emerging technologies allow digital production to be used within the initial stages of architectural design. The design process, in which drawing is the main tool, is affected with the rapid increase of digital production in the building sector and increasing awareness on digital drawing and production/fabrication is an undeniable fact of 21st century. In this context, the article investigates the status of hand (manual) and computer (digital) based drawings in architectural education; the students' perceptions and its effects on their performances. A case study -within the context of the Construction Systems II course given at the Architecture Department of Çankaya University-has been conducted to evaluate/quantify the students’ perceptions in order to demonstrate the advantages and disadvantages of hand and computer based drawings. Positive correlations of the familiarity to the drawing tool with easy correction of mistakes and relation of familiarity to the drawing tool with time management is observed. Based on the research; there is not a significant difference between hand based or computer based tools regarding spent time for the work in student practices; however, the process regarding revision, correction, or composition of drawing decreases time spent in computer aided drawing. Consequentlyit has been noticed that as the capability in drawing tool increased, the class performance of students increased too. The outcomes of the case study based on observations, evaluation, questionnaires and analysis covering an academicterm, are discussed in detail within the scope of the article.
Analysis of a historic masonry building
(Croatian Soc Civil Engineers-HSGI, 2011) Özmen, Cengiz; Er Akan, Aslı; Ünay, Ali İhsan; 56939; 4587
The paper starts from the observation that historic masonry buildings are often modified and altered to make them fit for present day use. A single-family masonry house in Turkey, situated in an earthquake prone area and built in the early 20(th) century, is studied. The analysis is made based on Turkish regulations for the initial building and for the building after alterations. Introduction of a reinforced-concrete slab has greatly improved seismic resistance of the building
Analytic Hierarchy Process (AHP) as an Assessment Approach for Architectural Design: Case Study of Architectural Design Studio
(Selçuk Üniversitesi, 2018) Harputlugil, Timuçin; 40295
Architectural design is complex and can be defined as an effective decision-making activity based on problem solving. This complexity is not based on content and volume of problems, but also heterogeneity and uncertainty of information provided for assessment, subjective approaches, and a large number of the criterion for assessment. The aim of this research paper is to contribute to the researches for assessment of architectural design by providing a novel approach based on Analytic Hierarchy Process (AHP) - a Multi Criteria Decision Making (MCDM) method. The approach supports an effective comparative analysis among the alternative projects based on determined criterion. The methodology is implemented with a case study in one of the design studios of Department of Architecture of Cankaya University on final design projects of a group of students with observation, research and assessment. The data used in the assessment is collected through interviews and surveys which is analysed by the help of a software. Based on the outcomes of the AHP-based approach, it has been seen that this approach can provide numerical results that are comparable, measurable, gradable, consistent and can be reported separately for each assessor. However, it has also been found that the AHP-based method is suitable for evaluating only a limited number of projects. With the research, and by setting thresholds levels for evaluation, it has become clear that successful and unsuccessful projects can be separated for achievement and competence. Consequently, it has been observed that the approach has considerable potentials to be further developed to evaluate architectural projects comparatively, especially for architectural students' projects, and other architectural projects such as architectural design competitions.
Architect - Structural Engineer Collaboration in Sustainable Structural System Design
(2011) Özmen, Cengiz; Ünay, Ali İhsan; 56939
This paper explores ways of collaboration between architects and structural engineers in the design of sustainable structural systems. Areas of collaboration are explored in terms of seismic design of new structures and rehabilitation of existing structures. Multidisciplinary design teams and an integrated design approach are critical to the process of sustainable building construction. The required group-work skills should be acquired by architects and engineers during their professional education. As a result, this paper also investigates ways in which the structural design education of architects and structural engineers can be redesigned to make their future professional collaboration more harmonious.
