Architect - Structural Engineer Collaboration in Sustainable Structural System Design
(Gazi Univ, 2011) Ozmen, Cengiz; Özmen, Cengiz; Unay, Ali Ihsan; Mimarlık
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
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
(2020) Bingöl, Kaan; Er Akan, Aslı; Ömercioğlu, Hilal Tuğba; 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.

Effects of Sound Absorption Materials on Reverberation Time According To Their Positions in the Square Plan and High Ceiling Rooms
(Gazi Univ, Fac Engineering Architecture, 2021) Kurtay, Cuneyt; Harputlugil, Gulsu Ulukavak; Yaman, Muammer
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).

Reflections on the Evidentiary Basis of Indoor Air Quality Standards
(Mdpi, 2022) Mahdavi, Ardeshir; Azar, Elie; Bandurski, Karol; Bourikas, Leonidas; Harputlugil, Timucin; Schweiker, Marcel; Berger, Christiane
Buildings are expected to provide healthy and comfortable indoor environmental conditions for their users. Such conditions have diverse dimensions, including thermal, visual, air quality, auditory, and olfactory aspects. Indoor environmental quality standards, guidelines, and codes typically inform professionals in the building design and operation phase in view of procedural, contractual, and legal boundary conditions. Given this critical role of standards, it seems significant to examine the applicability and scientific validity on a regular basis. In this context, the present paper focuses on the standard-based definition of indoor air quality (IAQ) indicators and their respective values. Hence, the main aim of this effort is to study several common national and international IAQ standards in view of the scope to which they include direct or indirect evidence for the validity and applicability of their mandates and requirements. To this end, selected IAQ standards were assessed via a structured schema that includes not only basic information, quality indicators, and suggested and recommended value ranges, but also any reference to scientific studies. The findings of this effort identify certain issues with the transparency of the chain of evidence from the results of technical literature and standard-based IAQ recommendations. Moreover, recommendations are made for the development of future transparent and evidence-based IAQ standards and guidelines.

Relationship Between Context-free/In-context Spatial Color Preferences and Color Constructs: the Extraversion Personality Trait Dimension
(Wiley, 2023) Demirbas, Guler Ufuk; Akbay, Saadet
Personality traits are considered the primary determinants of emotional and behavioral patterns of individuals within the built environment, influencing the experience of architectural space over their cognitive representation. Specifically, the dimension of extraversion within an individual's personality holds considerable predictive value in determining their attitudes toward the environment. Consequently, this study aims to investigate the influence of personality traits on color preference by comparing preferences for context-free color samples and in-context spatial colors among individuals exhibiting varying levels of extraversion. It also aims to ascertain the most accurate color-construct scale for delineating individuals' preferences for in-context spatial color. The study employed the International Personality Item Pool (IPIP) representation of lexical factor markers for the Big-Five structure. For the study, 11 colors, referred to as basic color terms, were selected as stimuli. Data on color preference were obtained through a rank order test for 11 context-free color samples and 11 virtual images of in-context spatial colors, as well as ratings of in-context spatial colors based on 14 color-construct scales. Findings reveal the relationship between extraversion personality trait and color preferences, revealing distinct patterns between context-free and in-context color preferences. They also suggest the possibility of divergent preferences for in-context spatial colors among individuals with varying levels of extraversion, with certain colors eliciting significantly different ratings on color-construct scales. The study's findings shed light on the importance of personality traits in predicting the relationship between architectural spaces and colors, depending on individuals' personalities, particularly within design disciplines such as interior architecture.
A Research on Comparison of Elevator Traffic Analysis Methods in Educational Buildings
(Gazi Univ, Fac Engineering Architecture, 2023) Harputlugil, Timucin; Deligoez, 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.

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
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.

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
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.
