Node pouring-free second-order recoverable steel coupling beam-PEC shear wall structure
The invention belongs to the technical field of structural engineering and structural seismic resistance, and particularly discloses a joint pouring-free second-order recoverable steel coupling beam-PEC shear wall structure which comprises a PEC shear wall, a steel coupling beam, a beam support, a connecting plate, an L-shaped friction joint plate and an SMA stranded wire, the PEC shear wall is provided with an outer side flange, the steel coupling beam is provided with a first web, an upper flange and a lower flange, and the first web is provided with a second web. Transverse end plates are arranged on the two sides of the first web plate, the beam support is provided with a second web plate, the connecting plate is connected with the end of the first web plate and the second web plate, the L-shaped friction gusset plate is used for connecting the upper flange with the upper portion of the outer side flange and connecting the lower flange with the lower portion of the outer side flange, and the SMA stranded wires are arranged on the outer side flange and the transverse end plates. The method effectively solves the problem that the post-earthquake steel coupling beam is difficult to repair due to excessive residual deformation caused by shear failure of the web.
本发明属于结构工程和结构抗震技术领域，具体公开了一种节点免浇筑的二阶可恢复钢连梁‑PEC剪力墙结构，包括PEC剪力墙、钢连梁、梁托、连接板、L型摩擦节点板以及SMA绞线，PEC剪力墙具有外侧翼缘，钢连梁具有第一腹板、上翼缘以及下翼缘，第一腹板的两侧均设置有横向端板，梁托具有第二腹板，连接板分别与第一腹板的端部与第二腹板连接,L型摩擦节点板用于上翼缘与外侧翼缘的上方连接以及用于下翼缘与外侧翼缘的下方连接，SMA绞线设置在外侧翼缘、横向端板上。本发明有效解决震后钢连梁由于腹板剪切破坏导致残余变形过大，进而难以修复的问题。
