Abstract

In India steel buildings are less common, though steel buildings may be economical in many instances. The study of the performance of steel buildings needs to be carried out to understand the seismic behaviour of steel buildings. One such study involves the effect of infill on the steel building performance. The Infill has significant influence on the response and performance of the buildings. In general it increases the stiffness of the system. However, it may shift the action from the column to beam. In the present study, the infill effect has been modeled by equivalent strut as per FEMA 356. SAP2000 version 14 has been used to evaluate the performance of the buildings. The study highlights the effect of infill on steel buildings including that on time period and nonlinear performance.
