One was composition of truss and shear wall. The other was composition of steel and concrete. In other a word, it was a double composite shear wall. In this paper, the seismic performance of shear walls with concealed steel truss was investigated. An experimental study of twelve 1:3 scale shear wall specimens with height-to-length ratios equal to 1.5 or 2.2 were carried out, four of which were normal shear walls, four of which were shear walls with concealed steel frame and four of which were shear walls with concealed steel truss. The shear wall specimens were given an axial compression ratio of 0.2 or 0.5. Based upon the experimental study, the effects of concealed truss and axial compression ratio on the load-carrying capacity, stiffness, ductility, hysteretic behavior, energy dissipation and failure mechanism of shear wall were discussed. The formulas of calculating load-carrying capacity and stiffness were established. The results obtained from the formulas and those from experiment were in good agreement. Some suggestions for seismic design of RC shear wall with concealed steel truss were put forward. The experimental results showed that, compared with normal RC shear wall, the seismic performance of the RC shear wall with concealed steel frame and concealed steel truss was greatly improved.
