Abstract

This study investigates the effects of high horizontal and vertical ground accelerations recorded in Antakya during the first mainshock of the 2023 Kahramanmaraş earthquakes (Pazarcık event) on a ten-story reinforced concrete building. Nonlinear time-history analyses were carried out for the building under three ground motion scenarios: (1) using the recorded horizontal and vertical components directly, (2) using the same records scaled to match a target spectrum, and (3) applying only the horizontal components. The results show that, when unscaled records are used, extent of damage and collapse, as well as story drifts and second-order effects, increase significantly compared to the scaled case. The vertical component plays a secondary role, and the collapse mechanism is governed primarily by horizontal ground motions.

Özet

Bu çalışma, 2023 Kahramanmaraş depremlerinin ilk ana şoku olan Pazarcık depremi sırasında Antakya’da kaydedilen yüksek yatay ve düşey yer ivmelerinin on katlı bir betonarme bina üzerindeki etkilerini incelemektedir. Bina için üç farklı yer hareketi senaryosu altında doğrusal olmayan zaman tanım alanında analizler yürütülmüştür: (1) kaydedilen yatay ve düşey bileşenlerin doğrudan kullanıldığı durum, (2) kayıtların hedef spektruma uyacak şekilde ölçeklendiği durum ve (3) yalnızca yatay bileşenlerin uygulandığı durum. Sonuçlar, gerçek kayıtların kullanıldığı durumda yaygın hasar, göçme, kat ötelemeleri ve ikinci mertebe etkilerinin belirgin biçimde arttığını göstermektedir. Düşey bileşenin ikincil bir rol oynadığı, göçme mekanizmasının ise esas olarak yatay yer hareketleri tarafından belirlendiği görülmüştür.
