Abstract
The RC short-pier shear wall structure is a new type of structural system in tall residential buildings. It has been applied in many buildings in China, but its seismic performance is worse than that of normal shear wall structures. Therefore, how to improve its seismic performance becomes a problem which has been paid much attention by engineers. In this paper, the seismic performance of short-pier shear walls with concealed bracing is investigated. An experimental study of four 1:3 scale coupled short-pier shear wall specimens has been carried out, two of which were normal coupled short-pier shear walls, and the other two coupled short-pier shear walls with concealed bracing. Based upon the experimental study, the effects of concealed bracing on the load-carrying capacity, stiffness, ductility, hysteretic behavior, energy dissipation and failure mechanism of shear wall are discussed. It is shown that the seismic performance of short-pier shear walls is greatly improved by concealed bracing. Finally, mechanical models for calculating the load-carrying capacity of the shear wall are proposed, and the theoretical results agree well with those from experiments.
