Abstract

This study investigates the effects of external frame irregularities on the seismic behavior of structural systems in reinforced concrete buildings with heavy overhangs. For this purpose, nonlinear time history analyses of two reinforced concrete buildings with heavy overhangs, designed with different external frame connection configurations, were conducted. The force-based fiber element method was used in numerical analyses, and the solutions were obtained using the SeismoStruct software. The acceleration records measured at the Türkoğlu station during the Kahramanmaraş-Pazarcık (Mw=7.7) earthquake were utilized as seismic loading. In the comparison of the seismic responses of the buildings, parameters such as top displacement, rotation, base shear force, base overturning moment, interstory drift, linear velocity and acceleration, as well as angular velocity and acceleration, were considered. Additionally, the number of damaged column and beam elements in both models was evaluated and compared according to the defined damage limit levels. As a result, it was determined that the lack of external frame continuity in reinforced concrete buildings with heavy overhangs significantly adversely affects the seismic behavior of the building.

Özet

Bu çalışmada kapalı ağır çıkma bulunan betonarme binalarda dış çerçeve düzensizliğinin yapısal sistemin sismik yükler altındaki davranışına etkileri incelenmiştir. Bu amaçla dış çerçeve bağlantılarının farklı olarak tasarlandığı ağır çıkma bulunan betonarme iki yapının zaman tanım alanında doğrusal olmayan analizleri gerçekleştirilmiştir. Nümerik analizlerde kuvvete dayalı fiber eleman yöntemi kullanılmış ve çözümler SeismoStruct programı ile elde edilmiştir. Deprem yüklemesi olarak Kahramanmaraş-Pazarcık (Mw=7.7) depreminin Türkoğlu istasyonunda ölçülen ivme kayıtları kullanılmıştır. Binaların deprem tepkilerinin karşılaştırmalarında tepe yerdeğiştirme, dönme, taban kesme kuvveti, taban devrilme momenti, göreli kat yerdeğiştirme, doğrusal hız ve ivme, açısal hız ve ivme değerleri dikkate alınmıştır. Ayrıca oluşturulan her iki modelde meydana gelen hasarlı kolon ve kiriş eleman sayıları belirlenen hasar sınır seviyelerine göre karşılaştırmalı olarak değerlendirilmiştir. Sonuç olarak, ağır çıkma bulunan betonarme binalarda dış çerçeve sürekliliğinin olmaması binanın deprem davranışı açısından önemli derecede olumsuz etkilere sebep olduğu belirlenmiştir.
