摘要
塑性铰支墙可用于替代传统RC剪力墙的底部加强区域,形成稳定的墙底塑性耗能区。通过设置只承担水平剪力和竖向荷载的抗剪组件和只承担弯矩的抗弯组件实现剪力墙弯剪解耦设计的目的。该文在已提出基于"弯剪分离"思想的塑性铰支墙的基础上展开了考虑面外变形的装配式塑性铰支墙体的抗震性能试验研究。该文介绍了两片1/3缩尺的墙体试件的拟静力试验,两个试件分别采用装配式混凝土剪力墙和装配式钢板剪力墙。试验结果表明:该文提出的装配式塑性铰支墙的连接方式是合理有效的,且该墙体试件在存在面外变形的情况下仍具有良好的抗震性能。
Plastic-hinge-supported walls can replace the bottom strengthening area of traditional RC shear walls and form a stable plastic energy dissipation zone at the bottom of the wall.By setting shear components that only bear horizontal shear and vertical load and bending components that only bear bending moment,a bending-shear-decoupling design is realized for shear walls.Based on the separation of bending and shear,the experimental study on the seismic performance of prefabricated plastic-hinge-supported walls considering the out-of-plane deformation is carried out.We introduce the quasi-static test of two 1/3 scale wall specimens,which used a concrete shear wall and a steel plate shear wall.The test results show that the connection mode of the prefabricated plastic-hinge-supported wall proposed in this paper is reasonable and effective,and that the wall specimen has good seismic performance even with the presence of out of plane deformation.
