The effect of muqarnas on acoustic quality of traditional Turkish bath interior space
(ACM Journal on Computing and Cultural Heritage, 2023-08-09) Ağırbaş, Aslı; Yildiz, E.; Architecture; AĞIRBAŞ, Aslı
Decorative “muqarnas” add charm to the design element and may influence the characteristics of an interior space. This study hypothesises that muqarnas in traditional Turkish baths (hammams) affect acoustic performances of such interior spaces. To test this hypothesis, a bath with muqarnas as the dome transition element was selected and a comparative study, in terms of acoustics quality with and without the decorative muqarnas, was conducted. Furthermore, the effect of different muqarnas configurations on acoustic quality of the interior space has been tested via optimisation simulations. With the use of optimisation model, a form of parametric muqarnas in the selected interior space was optimised according to the acoustic objectives. The optimisation tests were conducted with the objectives of increasing C50 (Clarity), C80, Reverberation Time (RT), Speech Transmission Index (STI), and decreasing RT. It was found that muqarnas do have an impact on acoustic performance of the interior space and the optimisation experiments suggest that different muqarnas configurations have different impact on the acoustic quality.

An experimental framework for designing a parametric design course
(2021-12) Ağırbaş, Aslı; Architecture; AĞIRBAŞ, Aslı
Architectural forms, architectural knowledge, design process, and design thinking are all changing with the use of computer-aided design programmes, and even traditional university architecture departments now wish to teach these programmes. However, it can be difficult to implement courses on such computer programmes because these departments have traditionally structured curricula. We developed a framework that can inform the design of a parametric design course which considers the university profile, the course profile, and the student profile. This framework evaluates the departments in three categories: ‘open to new design approaches’, ‘supportive of CAD’ and ‘reject new design approaches’. A parametric design course in relation to the proposed framework was designed and implemented as a case study. The process and the results were discussed.

Geometric decomposition and algorithmic model of main gate muqarnas of Ankara Cenabi Ahmet Pasha Mosque
(Elsevier, 2024-09-01) Asli Agirbas; Architecture; AĞIRBAŞ, Aslı
Cenabi Ahmet Pasha Mosque (Cenab-ıAhmet Pa¸s a Mosque) is known to be the only work that resembles the style of Architect Sinan in Ankara. In this study, it is aimed to examine the two-dimensional muqarnas scheme of the mosque’s main gate and to determine through algorithmic modeling the combination of muqarnas cells in the third dimension. By the photogrammetry method, the grid and star forms used in the muqarnas plan scheme are revealed. The geometric characteristic of the muqarnas in two dimensions is determined. Cell types of the muqarnas and their geometric configurations are obtained. It is demon- strated that there is a radial grid in the plan of the Cenabi Ahmet Pasha Mosque main gate muqarnas, and that the three-dimensional structure of the muqarnas consisting of six layers includes almond cell, triangle cell, deltoid cell, intermediate triangle cell, intermediate deltoid cell, biped cell and triped cell. Additionally, an algorithmic model based on the creation of cell unit system is proposed for the creation of the muqarnas geometry in 3D.

Interrelation between grid systems and star polygons of muqarnas ground projection plans
(Springer, 2022-1-21) Ağırbaş, Aslı; Yıldız, G.; Şahin, Murat; Architecture; AĞIRBAŞ, Aslı; ŞAHİN, Murat
Many muqarnas ground projection plans contain stars with unequal edge lengths in their compositions. In this study, the geometric reasons behind the unequality of star edge lengths in muqarnas ground projection plans have been searched. The main gates with complex-looking muqarnas belonging to the period of Suleiman the Magnificent (Kanuni Sultan Suleyman), designed by Architect Sinan in Istanbul, have been selected to examine. From the data obtained by 3D laser scanning and from the verification made, it has been confirmed that there are stars with unequal edge lengths in these muqarnas plans. From the geometrical examinations made according to the shape grammar theory, it was concluded that the muqarnas plans were created using spider-web grid and square grid layouts. It was also concluded that these grid types cause some of the star edge lengths to be unequal.

A methodology for 3D digital sketching practice in undergraduate architectural education
(Intellect Ltd., 2023) Ağırbaş, Aslı; Architecture; AĞIRBAŞ, Aslı
Paper-based sketches used in the first stage of architectural design have started to be replaced by digital sketches. Since many universities have switched to online education during the pandemic period, digital sketches have come to the fore in this period. It is seen that the architectural forms in the digital sketches are shaped according to the computer programme used, especially in undergraduate architecture education. This situation was identified as a problem in this study. As a solution to this, it is aimed to develop a method in order to develop the form-oriented creativity of the students in the computer environment. After the experimental case study, a questionnaire was conducted with the students to evaluate this method. It has been concluded that the exercise method proposed in this study can enable students to make digital sketches more easily.

A teaching methodology on the combination of architectural tradition and parametric design: A case study with birdhouses
(Intellect, 2022-01-01) Ağırbaş, Aslı; Architecture; AĞIRBAŞ, Aslı
Birdhouses were produced in Anatolia from the thirteenth century to the nineteenth century, each with period-specific features. The Industrial Revolution’s call for efficiency however, mandated that birdhouses were no longer manufactured. In this study, parametric design, which is based on an algorithmic design, is used to re-implement the lost practice of birdhouse construction. In the defined methodology, deployed in an undergraduate architectural course, this study considers all stages, from the design process through to the digital fabrication process, that occurs during the birdhouse design process based on metaball geometry created in visual programming language. I will present the problems encountered by the students and the solutions to these problems. In addition, I will evaluate the students’ attitude and response toward the teaching methodology statistically with SPSS Statistics (Statistical Product and Service Solutions).

The use of parametric mapping as an analysis method in contextual design studio
(Proceedings of SiGRaDi) Şahin, Murat; Ağırbaş, Aslı; Kaynar, Hilal; Architecture; ŞAHİN, Murat; AĞIRBAŞ, Aslı; KAYNAR, Hilal
This paper is discussed an experimental study carried out in the undergraduate Contextual Design Studio (CDS). The studio comprises four stages: Site Analysis Phase, Conceptual Design Studies, Design Development Phase, and Final Presentation. The site analysis stage lasts for about four weeks,10 hours a week in the studio. Particular importance is given to this part of the project so that students have a chance to gain different perspectives on multiple meanings of context and, more specifically, the historical, social and physical context of the the neighborhood. Besides conventional mapping and representation techniques and tools, some new design tools have been introduced in the studio, one of which was this experimental study in question. The study aims at the integration of the Parametric Mapping techniques, at a basic level, into the site analysis process in the contextual design studio to provide an entry point to thinking through the tool used for the students. In this term, the method of abstracting site features through Parametric Mapping was used in the site analysis process and the effect of this form-oriented data on the concepts of the projects was interpreted. NudiBranch, an add-on to the Grasshopper program, was used in the Parametric Mapping workshop. Students' works were discussed briefly with the help of some representative instances.
