Seismic Performance of In-Filled Steel-Concrete Composite Columns Using Fiber Analysis Method

Abstract:

The study for cyclic load-displacement relationship and seismic characteristics of square Concrete-Filled Steel Tubular (CFT) columns is experimentally and analytically conducted. Nine CFT column specimens are tested under constant axial loading and monotonically increasing lateral loading. For predicting the strength and ductility of CFT columns, fiber analysis technique is used. The analytical results show reasonable agreement with experiment results and the moment capacity of CFT columns is predicted with reasonable accuracy using the fiber model. The influence of the steel tube on the lateral response of CFT columns is studied for the evaluation of seismic performance.
