A shear wall with concrete filled steel tube (CFST) columns and encased steel truss is a new type of shear wall. To determine the seismic performance of the new shear wall, an experiment was carried on a 1/5-scale model. Based on the experimental study, the load-carrying capacity, stiffness, ductility, hysteretic property, energy dissipation and failure phenomena of the model were analyzed. It shows that the seismic performance of a shear wall with CFST columns and encased steel truss has high bearing capacity, stiffness, energy dissipation capacity and good ductility. In addition, a numerical elastic-plastic finite element (FE) analysis of a shear wall with CFST columns and encased steel truss were carried out. The computation results were in good agreement with the test results. FE software, ABAQUS, was used to change the ratio of steel truss to steel tubes and normalized axial force. The influences of different parameters of shear walls were carried out.
