Study on Seismic Performance of CFST Frame and Truss

Ya Bin Yang, Wan Lin Cao

Abstract

Concrete filled steel tube (CFST) got a good application in actual project. In order to further the seismic performance of the CFST, experiment was carried on two 1/5 scale models, which included one CFST frame, one CFST truss. Based on the experimental study, load-carrying capacity, stiffness, ductility, hysteretic property, energy dissipation and failure phenomena of each model were analyzed. The study shows that the seismic performance of CFST truss has high bearing capacity, stiffness, energy dissipation capacity and good ductility.
