摘要 

 传统钢筋混凝土剪力墙底部在罕遇地震作用下可能出现不可修复的损伤,不利于建筑结构在震后的快速恢复。本文提出一种损伤可控的塑性铰支墙,将墙肢的抗弯与抗剪能力分离,降低弯剪耦合,使构件力学需求更加明确,利于性能化设计和实现预期的损伤模式|同时将塑性损伤集中于专门的消能减震装置上,提高结构震后可恢复能力。对三片1/3缩尺的墙片试件进行了拟静力试验。通过与同尺寸钢筋混凝土墙片试验结果的对比,证明等强度设计的塑性铰支墙具有更好的滞回耗能能力,同时其损伤分布得到有效控制,墙体弹性部分和连接构造的工作性能良好。

Abstract: 
Irreparable seismic damages were frequently observed on the bottom of code compliant reinforced concrete (RC) shear walls in major earthquakes. These damages have negative effect on the resilience of RC structures. As a superior substitute for the conventional RC wall, a plastic hinge-supported wall is proposed in this paper. It tries to distribute the bending moment and shear force to certain structural components so as to decouple the complex bending-shear mechanism. It becomes easy to determinate the precise demand of component design and realize a performance-based design and the strong shear-weak bending mechanism. Meanwhile, plastic damage can be concentrated on energy dissipation devices so as to improve the resilience of structures. To experimentally examine the seismic performance of plastic hinge-supported wall, three wall specimens were produced and tested quasi-statically. The results demonstrate that the Pin-supported Plastic Hinge Walls show a better hysteretic energy dissipation capacity comparing with the RC wall counterpart of the same strength, and the distribution of plastic damage can be controlled. In addition, the elastic-designed RC parts and connection measures show stable performance.
