    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
    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.

    A Simple Selection Method of PV Systems for University Campuses
    (Gazi Univ, 2023) Harputlugil, Gülsu Ulukavak; Bara, Marıam; Ulukavak Harputlugil, Gulsu
    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.

    Rock-Cut Facades: Conveyors of 'false Monumentality in Byzantine Cappadocia
    (Cambridge Univ Press, 2022) Ozturk Buke, Fatma Gul
    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.

    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
    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
    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.

    A Research on Comparison of Elevator Traffic Analysis Methods in Educational Buildings
    (Gazi Univ, Fac Engineering Architecture, 2023) Harputlugil, Timucin; Deligoez, Dostcan; Deligöz, Dostcan
    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.

    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
    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.
