Abstract: In this paper, a new composite shear wall with concealed steel truss was put forward. It included two kinds of composition. One was composition of steel truss and RC shear wall, the other is composition of profiled steel and concrete. In order to compare the seismic performance of shear walls with concealed steel truss, normal shear wall and steel truss, experimental study on seismic behavior of three 1/3 scale specimens, including a normal shear wall, a shear wall with concealed steel truss and a steel truss, were carried out based upon the experimental study, the bearing capacity, hysteretic property, energy dissipation and failure mode of the specimens were contrastively analyzed. The experimental results show that the seismic bearing capability and energy dissipation capacity of shear wall with concealed steel truss excelled the total of normal shear wall and steel truss.
