Bacalar, atık ve sıcak
gazları atmosfere çekmek için kullanılmakta olup fabrikaların en önemli kısmını
oluşturmaktadır. Günümüzde, çevre ihtiyaçları ile ilgili kodların
gereksinimlerini karşılamak için, bu narin yapıların yüksekliği artmakta, bu da
onları dinamik sismik yüklere karşı daha savunmasız hale getirmektedir. Bu
sebepten dolayı, bu uzun ve narin yapıların genel dinamik davranışı, zemin
etkisi de dikkate alınarak anlaşılmalıdır. Bu çalışmada, bir model bacanın
dinamik davranışı, açıklıklar, baca temeli ve zemin etkisiyle ayrı ayrı ele
alınarak belirlenmiştir. Bu çalışmanın bulguları, zemin-yapı etkileşiminin
(ZYE), betonarme bacaların dinamik davranışını etkileyen önemli bir olay
olduğunu ortaya çıkarmıştır.

Effect of soil-structure interaction on the seismic behavior of RC chimneys

Öz

RC chimneys are occupying the most important part of industrial factories that they are utilized for removing the
waste and hot gases to the atmosphere. Nowadays, in order to meet the requirements of the codes related with the
environment needs, the height of these slender structures increase that makes them more vulnerable to seismic
loads. Therefore, the overall dynamic behavior of these tall and slender structures should be understood by also
considering the effect of underlying soil. In this study, the dynamic seismic response of a model chimney was
determined by considering openings, foundation and underlying soil separately. Findings of this study revealed
that soil-structure interaction (SSI) is an important phenomenon that effects the dynamic response of reinforced
concrete (RC) chimneys.
