STUDY ON THE MECHANICAL BEHAVIOR OF SELF-CENTERING WALL UNDER CYCLIC LOADING

The self-centering wall is simplified as a rigid body, while the horizontal load vs. rotation curve of the self-centering wall subjected to cyclic loading is obtained by theoretical derivation. Three cases are taken into account to investigate the mechanical behavior of the self-centering wall, i.e. only considering the self-weight of the self-centering wall, considering the effect of prestressed tendons, and considering both the influence of prestressed tendons and dampers. The study presented in this paper indicates that for the self-centering wall, the prestressed tendons provide the self-centering ability along with the gravity of the wall, while the dampers can dissipate energy. In addition, the mechanical performance of the self-centering wall depends on the dimensions of wall, the design parameters of prestressed tendons and dampers.
