Özet:

 It is well known that structural displacement or ductility demands of structures subjected to near-fault ground motions are generally greater than ordinary ground motions. Therefore, the effect of earthquake records in the near region on the seismic behavior of structures has been widely studied in the last decades. Peak ground acceleration PGA is an important key parameter, which determines structural behavior. However, structural behavior depends on the distance of the structure to the fault zone, the ratio of peak ground velocity PGV to peak ground acceleration, the velocity pulse duration of ground motion, and the natural period of the structure. In this study, the seismic behavior of buildings with flat slab systems was investigated under near-fault ground motions. Linear time history analysis was performed for a 30-storey building designed according to TBEC-2018 using SAP 2000 finite element analysis software. Results were compared with the behavior of the building with a solid slab system. It is concluded that the ratio of PGVPGA is very effective on the flat slab systems.

 Yakın fay yer hareketlerine maruz yapıların yapısal yer değiştirme veya süneklik taleplerinin genellikle normal yer hareketlerine nazaran daha büyük olduğu iyi bilinmektedir. Bu nedenle, faya yakın bölgelerdeki deprem kayıtlarının yapıların sismik davranışı üzerindeki etkisi son yıllarda yaygın olarak araştırılmaktadır. En büyük yer hareketi ivmesi PGA, yapısal davranışı belirleyen en önemli parametrelerden bir tanesidir. Bununla birlikte yapısal davranış, yapının fay bölgesine olan mesafesine, en yüksek yer hareketi hızının PGV en yüksek yer hareketi ivmesine oranına, yer hareketinin hız darbe süresine ve yapının doğal periyoduna bağlı olmaktadır. Bu çalışmada, düz döşemeli binaların yakın fay yer hareketleri altındaki sismik davranışları incelenmiştir. SAP 2000 sonlu elemanlar analiz paket programı kullanılarak TBDY-2018e göre tasarlanan 30 katlı bir bina için doğrusal zaman tanım alanında analizler yapılmıştır. Elde edilen sonuçlar, kirişli döşemeli binadan elde edilen sonuçlar ile karşılaştırılmıştır. PGVPGA oranının düz döşemeli sistemler üzerinde oldukça etkili olduğu sonucuna varılmıştır.
