Değişken dolgu duvar özellikli betonarme yapıların deprem güvenliklerinin değerlendirilmesi
Earthquake Vulnerability Assessment Of RC Structures With Variable Infill Wall Properties

HAKAN DİLMAÇ [1] , Fuat DEMİR [2]


Betonarme yapılarda dolgu duvarlar genellikle yapının mimari gereksinimlerinden dolayı bölme elemanları olarak kullanılmaktadır. Dolgu duvarların deprem etkisine karşı daha zayıf olduğuna dair bir fikir birliği olmamasına rağmen yapının deprem davranışını genellikle olumlu etkilediği düşünülmektedir. Bu nedenle dolgu duvarların betonarme yapıların yapısal davranışına katkısının anlaşılması çok önemlidir. Bu çalışmada dolgu duvarın basınç dayanımı ve kalınlığı gibi mekanik özelliklerinin yapıların deprem davranışa ve performansına olan etkisi incelenmektedir. Bu amaçla, farklı yapısal özellikler sahip konut türü mevcut betonarme binalar seçilmiştir. Değişken özelliklere sahip dolgu duvarlı mevcut betonarme yapıların yapısal ve deprem davranışını incelemek için mimari planları da dikkate alınarak doğrusal olmayan analizler yapılmıştır. Dolgu duvarlı ve dolgu duvarsız çerçeve sistemlerin incelenmesi yapılmış ve karşılaştırılmıştır. Yapılan çalışmanın sonucunda dolgu duvarlar betonarme yapıların deprem performansına olumlu katkısı sağladığı ve duvarın basınç dayanımı ile kalınlığının yapısal davranışı önemli ölçüde etkilediği görülmüştür.

The infill walls are often used to the aim of dividing the residential area to provide the architectural requirements according to purpose of use in residential RC structures. Although there is conflict about the infill walls occur a RC structure less vulnerable to earthquake impacts, the beneficial influence of the infill walls on dynamic and static behaviors of RC structures is generally thought. Therefore, understanding the contribution of the infill wall to structural behavior of RC structures is very significant in terms of the structural safety. This study investigates the influence of infill wall having variable mechanical properties as compressive strength and thickness on structural behavior and earthquakes performance of low-rise residential RC structures. In the study, the selected RC structures for earthquake vulnerability assessment are existing residential buildings. The nonlinear analyzes are carried out by considering architectural plan of each of RC structure to determine influence of infill wall having variable properties on the structural and earthquake behavior. The analyzes are also made for the bare-frame cases of RC structures and are compared with behavior of infilled frames of them. When the results obtained in the this study are evaluated, the existing infill walls and differences in the its mechanical properties significantly affected earthquake vulnerability the RC structures, positively.
