Investigation of the Earthquake Performance Adequacy of Low-Rise Rc Structures Designed According To the Simplified Design Rules in Tbec-2019
(Mdpi, 2022) Yel, Nur Seda; Arslan, Musa Hakan; Aksoylu, Ceyhun; Erkan, İbrahim Hakkı; Arslan, Hatice Derya; Işık, Ercan
In this study, earthquake performance of the structures was tested which were modeled according to the minimum criteria of simplified analysis approach proposed in TBEC-2019. For this purpose, 144 reinforced-concrete building models were designed according to parameters such as earthquake design class, building height (number of storey), number of spans, soil type and three different simplified formulas suggested in the code. The level of structural performance of buildings models was determined by the linear (L) and nonlinear performance analysis (NL) methods that given in TBEC-2019. The base shear force, top displacements and over-strength factor (omega) of each structural model were obtained, and performance analysis was performed by comparatively. As a result of the structural analyses, it was seen that some of the buildings model designed according to minimum column sectional criteria given in simplified methods could not meet the suggested seismic performance level. While the number of structural models that provide the controlled damage (CD) level in the L analysis method is 44 (30.55%), it is 107 (74.3%) in the NL analysis method. The insufficient performance was obtained in both L and NL methods in models which have over-strength values below 3. It has been observed that multi-criteria of building performance are not met with the weakening of local soil conditions. It was also seen that the L method chosen in the performance analysis gave more conservative results with this study.
A Lens Model Approach on Estimating Perceptions of Turkish Primary School Students and Architects on Ideal Primary Classroom Settings
(Konya Technical University Faculty of Architecture and Design, 2012) Arslan, Hatice Derya; Çınar, Kerim; Dinç, Pınar
The study has been perfonned on prirnary school students and designers (architects) in order to define the conıponents and design factors of the ideal classroonı setting in which prirnary school students will willingly study and to decide which setting and design factors are nıost suitable for effective learning. To this end, the following hypothesis was developed: "Classroom setting perceptions of students and designers differentiate in terms of setting and design factors". Visuals of 20 different classroonı settings fronı Turkey - the physical properties of which were pre-defined in detail by the control group - were used in the scope of the study. A questionnaire fonn was used to collect students' and designers' (architects') evaluations on the visuals; collected

School Buildings Performance in 7.7 Mw and 7.6 Mw Catastrophic Earthquakes in Southeast of Turkey
(Elsevier, 2023) Öztürk, Murat; Arslan, Musa Hakan; Doğan, Gamze; Ecemiş, Ali Serdar; Arslan, Hatice Derya
Although Turkey is located in one of the active earthquake belts of the world, the 7.7 and 7.6 magnitude earthquakes that occurred on February 6, 2023, 9 h apart, as rarely seen in the seismology literature, caused one of the biggest disasters in Turkey's history. In the earthquakes affecting an area of approximately 110,000 square kilometers, serious damage and collapse occurred in public buildings as well as other structures. There are more than 12,000 school buildings in the earthquake-affected area and this number constitutes an important part of public buildings. This article deals with the damage types and causes of various public school buildings that were exposed to the earthquakes in southern Turkey on February 6, 2023. The seismicity of the region and the effects of the 6 February earthquakes were discussed, and the response spectra of the different regions most affected by the earthquakes were compared with the design spectra defined in the codes. In addition, during the field investigation the damage types and causes of damage in school buildings were listed in sections and the observations made with performance based analytical studies were supported. From field reconnaissance, the importance of understanding the deficiencies of school buildings, which have social priority, in order to avoid tragic consequences in possible earthquakes has been revealed.
