Abstract
Bu çalışmada, 2019 yılında yürürlüğe giren Türkiye Bina Deprem Yönetmeliği (TBDY-2019) ile 2007 Türk Deprem Yönetmeliğinin (TDY-2007) deprem hesap yöntemleri açısından karşılaştırılmasına odaklanılmıştır. Bunun için aynı plan özelliklerine sahip 3-4-5 katlı çerçeve + perde türü betonarme binalar üzerinde ETABS programında lineer elastik analizler gerçekleştirilmiştir. Analizlerde TBDY-2019 için zemin sınıfı ZA, deprem tasarım sınıfı 1 (DTS1), TDY-2007’de ise zemin sınıfı Z1, deprem bölgesi 1. derece olacak şekilde İstanbul/Kartal bölgesi dikkate alınmıştır. Modellemeler sonucu binaların her iki yönü için Eşdeğer Deprem Yükü yöntemi (EDY) ve Mod Birleştirme yöntemi (MBY) kullanılarak taban kesme kuvvetleri, periyot ve göreli kat ötelenme değerleri hesaplanmıştır. Binaların her iki yöndeki EDY’den elde edilen taban kesme kuvvetleri x ve y yönü için sırasıyla %40-43 ve %39- 47 oranında TBDY-2019’da daha az sonuç vermiştir. MBY’de ise bu oran sırasıyla %38-46 ve %35-45 şeklindedir. TBDY-2019 yönetmeliğindeki çatlamış kesit rijitliği kullanımı kat deplasmanlarının ve sistem periyodunun artmasına, taban kesme kuvvetlerinin ise azalmasına yol açmaktadır.
This study aims to compare the Turkish building seismic standards that come into force by the year 2019 (TBEC-2019) with Turkish Earthquake Code of 2007 (TEC-2007) according to earthquake calculation methods. For this purpose, linear elastic analyzes were carried out in the ETABS program on 3-4-5 story frame + shear wall type reinforced concrete buildings with the same plan features. For TBEC-2019, soil type is considered as ZA, seismic design class 1 (DTS1), in TEC-2007 soil class Z1, earthquake zone as 1st degree taken into account district of Kartal located in Istanbul. As a result of the modeling, base shear forces, period, and relative story drift calculated were made using the equivalent earthquake load method and mode combination method for both sides (X and Y) of the buildings. The base shear forces obtained from the equivalent earthquake load method in x and y directions of the buildings resulted in 40% -43% and 39-47% fewer results at TBEC-2019, respectively. In the mode combination method, this ratio is 38% - 46% and 35-45%, respectively. This situation can be explained by the fact that the use of cracked section stiffness in the TBEC2019 regulation, leads to an increase in story displacements and natural vibration period, and a decrease in base shear forces.
