According to performance-based seismic design theory,six specimens of high performance concrete shear wall with boundary columns and several high strength rings like a chain along boundary element in the potential plastic region were designed and the quasi-static tests were carried out.

为了改善高性能混凝土剪力墙的延性,按性能设计理论,在剪力墙截面两端设置端柱,并在构件的塑性铰区采用分段约束高强箍筋,设计了6个带端柱高性能混凝土剪力墙试件,进行了拟静力试验;对其破坏形态、滞回特性、变形能力、刚度退化、耗能能力、截面应变等进行了研究。
