(Croatian Soc Civil Engineers-hsgi, 2011) Ozmen, Cengiz; Özmen, Cengiz; Akan, Asli Er; Akan, Aslı; Unay, Ali Ihsan; 56939; 4587; Mimarlık; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
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.

Architect - Structural Engineer Collaboration in Sustainable Structural System Design
(Gazi Univ, 2011) Ozmen, Cengiz; Özmen, Cengiz; Unay, Ali Ihsan; 56939; Mimarlık; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
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.
Architectural Design - Structural System Conformity Problems Encountered in the Design and Application Processes of Stick Aluminium Curtain Wall Systems in Turkey
(Gazi Univ, Fac Engineering Architecture, 2022) Ozmen, Cengiz; Saban, Muge; 56939; 01. Çankaya Üniversitesi; 05. Mimarlık Fakültesi; 05.02. Mimarlık
Stick aluminium curtain wall (SACW) systems are common curtain wall systems in Turkey. These sytems offer many advantages including architectural variation, modular design, ease of production and assembly. Beside their architectural properties SACW systems create significant load effects on structural systems. These load effects include lateral loads such as seismic and wind loads as well as static vertical loads. This load transfer is not one way. The vertical and lateral displacements of building structures also act on curtain walls. Healthy load transfer between the SACW and the building depends on architectural decisions during the design and construction process. Due to their wide use SACW systems are prone to architectural mistakes. These mistakes often represent themselves at latter stages of the construction and require solutions which will affect the architectural characteristics and structural behavior of buildings. This study focuses on SACW design and construction processes to find the effects of architectural decisions on curtain wall behavior. Case studies that include architectural design mistakes are selected to classify and study the reasons and the solutions of these mistakes. The importance of cooperation between all the stakeholders including the architects and engineers is emphasized for the prevention of these mistakes.

Artificial Intelligence Applications in Earthquake Resistant Architectural Design: Determination of Irregular Structural Systems With Deep Learning and Imageai Method
(Gazi Univ, Fac Engineering Architecture, 2020) Bingol, Kaan; Akan, Asli Er; Ormecioglu, Hilal Tugba; Er, Arzu; 154406; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
Although the architectural design process is carried out with the collaboration of experts who are experienced in many different areas from the main preferences to the detailing stage, the major decisions such as plan organization, mass design etc. are taken by the architect. Computer Aided Design (CAD) programs are generally effective after the major decisions of the design are taken. For this reason, it is common for the main decisions, taken during the design process, to be changed during the analysis of the structural system. In order to prevent this, in the early stages of architectural design, earthquake system awareness and structural system design should be included as an design input; as, the failure of the structural system which did not considered well in the architectural design phase leads to unexpected revisions in the implementation project phase and thus leads to serious losses in both time and cost. The aim of this study is to create an Irregularity Control Assistant (IC Assitant) that can provide architects general information about the appropriateness of structural system decisions to earthquake regulations in the early stages of design process by using the deep learning and image processing methods. In this way, correct decisions will be made in the early stages of the design and unexpected revisions that may occur during the implementation project phase will be prevented.

(Gazi Univ, Fac Engineering Architecture, 2021) Kurtay, Cuneyt; Harputlugil, Gulsu Ulukavak; Yaman, Muammer; 36110; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
In rooms with speech action, subjective and objective room acoustics parameters should be considered in the creation of acoustic performance. In this study, an evaluation has been made over the reverberation time for the speech action of the existing Iraq-Najaf Islamic University Alawiya Conference Hall. Within the scope of the study, the control of the reverberation time affecting the subjective and objective room acoustics parameters has been examined, the relationship between the reverberation time and the surface absorptions of the room have been examined. Reverberation time on existing situation was determined by making in situ measurements. In order to control the reverberation time of the existing hall, the materials selected according to the sound absorption coefficients have been positioned differently and alternative models have been developed. The reverberation times of the alternative models were determined using the ECOTECT v.5.20 computer simulation program used for acoustic analysis, and their geometric acoustics analysis was performed using the ray tracing method. By comparing the models, the surface absorptions have been analyzed to obtain the appropriate reverberation time in room for speech action. As a result of the study, the effects of the use of walls, ceiling and floor finishing materials and surface absorptions on the reverberation time have been evaluated within the scope of improvement for speech action in the halls with square plan, flat floor and high ceiling (min 6 m).

Fostering Creative Cognition in Design Education: a Comparative Analysis of Algorithmic and Heuristic Educational Methods in Basic Design Education
(Middle East Technical Univ, 2021) Uysal Urey, Zeynep Cigdem; 18663; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
This research aims to examine the impact of algorithmic and heuristic educational methods in basic design education in an attempt to see their effects on the development of the creative cognition of students. The impact of educational methods in the development of creativity and creative problem-solving ability in design education has been addressed by a limited number of studies. The impact of algorithmic and heuristic educational methods in basic design education, on the other hand, has not been studied as of yet. In order to investigate this impact, this research conducts both a systematic theoretical review and a qualitative analysis on the use of algorithmic and heuristic educational methods in basic design education. The systematic theoretical review has been conducted both in the studies of design cognition and creativity and also in the studies of design education. The qualitative analysis has been carried out in the first-year basic design studio, with an attempt of making a comparison between the impacts of algorithmic and heuristic educational methods, through a creativity assessment of projects, based on the criteria of novelty and appropriateness. The analysis was made respectively on the pre-final projects of Fall 2016-2017 semester, which was carried out by means of an algorithmic educational method, and Fall 2017-2018 semester, which was carried out in line with heuristic educational method. The results of the comparative analysis have shown that both the overall novelty levels of the projects and also the average grade values were higher in the heuristic group in comparison to the algorithmic group. These results might imply that heuristic education would affect the overall creativity levels of projects in a positive way, and the students who are instructed heuristically would be able to show more exploratory behavior, generating more novel solutions than students who were instructed algorithmically.

The Layers of Cordoba: an Analytical Historical Study for The Effect of Religion Conflict on Architectural and Urban Features
(Vilnius Gediminas Tech Univ, 2019) Murad, Mahmoud; Batirbaygil, Mehmet; Pilehavrian, Nuran; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
This paper discusses Cordoba as one of the most iconic cities in human history and particularly in Europe. As part of the Andalusia region in southern Spain, Cordoba was the center of many conflicts that helped in shaping the European architecture and the urban fabric. Under the Umayyad rule, Cordoba was the largest and arguably most beautiful city in the World. However, the passage of time has not been very kind to it. Unfortunately, it has suffered from severely diminished of its historical and strategic value. This paper analysed Cordoba's history through different ages. Then, we focused on the peak of the city when it was under the Islamic rule when it became the center for culture and arts. At the end, we analysed how the city has faced a drastic architectural transformation that was carried out by the Spanish when they took control of the city during the Spanish Reconquista. We found how different cultures and religions throughout history have affected the architectural layers of Cordoba. These layers have exposed either demolish, overlap or dominate of one layer over another layer. Finally, we realized that this conflict created present Cordoba; the strong cultural, economic, touristic center in Southern Spain.

A Research on Comparison of Elevator Traffic Analysis Methods in Educational Buildings
(Gazi Univ, Fac Engineering Architecture, 2023) Harputlugil, Timucin; Deligoez, Dostcan; 40295; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
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, Timucin; Harputlugil, Gulsu Ulukavak; 40295; 36110; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
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.
Rock-Cut Facades: Conveyors of 'false Monumentality in Byzantine Cappadocia
(Cambridge Univ Press, 2022) Ozturk Buke, Fatma Gul; 140902; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
The monumental rock-cut facades of the tenth to eleventh century-mansions - so-called courtyard complexes - in Cappadocia, central Turkey, are rare examples of secular Byzantine architecture. While these symmetrically designed facades adorned with superimposed arches differ from the simpler ones (both carved and built) in the region, they bear striking similarities to others from the broader Mediterranean basin. This article offers new insights into the discussion on the uniqueness of the rock-cut facades of courtyard complexes and reconsiders the raison d'etre of this 'false' monumentality in the rural setting of Byzantine Cappadocia.

The Role of Aerodynamic Modifications in the Form of Tall Buildings Against Wind Excitation
(Middle East Technical Univ, 2007) Ilgin, H. Emre; Gunel, M. Halis; 01. Çankaya Üniversitesi
Modern tall buildings go higher and higher with the advances in structural design and high strength materials. However, every advance in height comes with a new difficulty. Efficient structural systems, high strength materials, and increased height, result with decrease in building weight and damping, and increase in slenderness. On the other hand, as the height and slenderness increase, buildings suffer from increased flexibility, which has negative effects in wind loading. Flexible structures are affected by vibration under the action of wind which cause building motion, and plays an important role in the structural and architectural designs. Understandably, contemporary tall buildings are much more vulnerable to wind excitation than their predecessors. Hence, different design methods and modifications are possible in order to ensure the functional performance of flexible structures and control the wind induced motion of tall buildings. An extremely important and effective design approach among these methods is aerodynamic modifications in architecture. In this context, the authors classify these aerodynamic modifications in architecture for resisting the lateral loads. Wind safe tall building design begins with the architect, and the influence of the wind action must be taken into consideration from the very beginning of the architectural design process by considering building aerodynamics.

Towards an Earthquake-Resistant Architectural Design With the Image Classification Method
(Taylor & Francis Ltd, 2024) Akan, Asli Er; Bingol, Kaan; Ormecioglu, Hilal Tugba; Er, Arzu; Ormecioglu, Tevfik Oguz; 154406; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
Architectural design is an interdisciplinary process which involves multiple stages that are interconnected. In this process, it is common for major decisions to be changed during the final stage, the analysis of the structural system. After making substantial corrections, the architect has to revisit the early stages, the preliminary project. This back-and-forth process can result in significant losses in time and cost. The proposed Irregularity Control Assistant (IC-Assistant) aims to provide architects with feedback on the conformity of structural system decisions to the irregularities defined in the Turkish Building Earthquake Code (TBEC-2018), using image processing methods at the early stages of the design process. The IC-Assistant was preliminarily created to evaluate the torsional irregularity of plan organization using deep learning methods. In this study, the results of the IC-Assistant were verified by structural analysis with the Prota-Structure program. The novelty of this study is the use of the image-classification method in earthquake-resistant architectural design. Up to this point, the method has been mainly used in facial recognition systems. This method minimizes time, human error, and cost losses and includes awareness of load bearing and earthquake resistance as inputs in the early stages of architectural design.
