摘要：

Low-cyclic reversed load testing was carried out on a 1/2-scale four-story spatial model of the bottom of a new precast concrete shear wall structure. The test results are compared with the push-over analysis results of the prototype model to determine the seismic performance of the specimen. The new precast concrete shear wall structure, which meets the requirements of the current Chinese seismic fortification code and possesses excessive bearing capacity due to the effects of non-structural walls and effective confinement of local cast-in-situ regions, can be safely applied to practical engineering. As concrete infill walls prefabricated together with precast shear wall panels were used, it is necessary to pay sufficient attention to the effects of non-structural walls on the strength and stiffness of the main structure when designing according to current Chinese standards. Furthermore, the strength and stiffness of new precast concrete shear wall structure have been enhanced within the elastic phase, which has made its performance in the elastic-plastic phase complicated. Therefore, it is strongly recommended to perform detailed seismic effect analysis on a refined elastic-plastic model for this precast concrete shear wall structure. ©, 2015, Tsinghua University.
