Investigation of effect of infilled wall on soft story irregularity

Abstract

Earthquake is one of the most destructive natural disaster types. Reducing the devastating impact of earthquake impact on structures is an important issue for earthquake engineering. Sufficient rigidity, strength and ductility are expected from structures under earthquake effect. Irregularities that will have a negative effect on the behavior of the structure should be avoided in order to perform the necessary behavior of the structure. The irregularities occurring in the structures are soft story irregularity, weak story irregularity, irregularity in the plan, short column behavior, mass irregularity. The occurrence of these irregularities in the structures makes the earthquake effect more destructive. The removal of the infilled walls on the ground story in the structures image lead to soft story irregularity and weak story irregularity in the structures in order to obtain commercial purposes and aesthetic image. In the earthquakes experienced in the past years, damage caused by soft story irregularities occurred. The loss of life and property in these buildings was very high. In this study, the effect of infilled walls and ground story height on the occuring of soft story irregularities was investigated. 4 different ground story height model was created. In these models, the infilled walls and absence of infilled walls on the ground story were investigated separately.
