Abstract
Shear wall with concrete filled steel tube columns and concealed trusses is a new kind of shear wall. In order to further the seismic performance of the new shear wall, experiment was carried on three 1/5 scale models, which included one traditional RC shear wall, one shear wall with concrete filled steel tube columns, one shear wall with concrete filled steel tube columns and concealed trusses. Based on the experimental study, load-carrying capacity and hysteretic property of each model were analyzed. The study show that the seismic performance of shear wall with concrete filled round steel tube columns and concealed steel trusses has high bearing capacity and good hysteretic property. Load carrying capacity calculation of shear wall with concrete filled steel tube columns and concealed steel trusses were carried out, the calculate results were in good agreement with the measured results.
