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

Abstract

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.
