Abstract

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.

Değişken dolgu duvar özellikli betonarme yapıların deprem güvenliklerinin değerlendirilmesi

Abstract

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.
