Inner arch type steel frame-combined steel plate shear wall and mounting method thereof
The invention discloses an inner arch type steel frame-combined steel plate shear wall and an installation method thereof.The shear wall comprises columns, beams and a shear wall body, the columns are arranged at the left end and the right end of the shear wall body, the beams are arranged at the upper end and the lower end of the shear wall body, the shear wall body comprises butterfly-shaped plates, and the butterfly-shaped plates are installed between the columns which are oppositely arranged on the same layer; energy dissipation pieces are installed on the front side and the rear side of the center of the butterfly-shaped plate respectively, a beam connecting plate is installed between the butterfly-shaped plate and the beam, and the beam connecting plate is of a sandwich plate structure. According to the steel frame combined steel plate shear wall, the hysteretic curve pinching phenomenon caused by out-of-plane buckling of the steel plate can be improved through the inner arch effect, a plastic hinge of the steel frame combined steel plate shear wall can be transferred into the combined steel plate shear wall from a steel frame beam, and the bearing capacity, the energy dissipation capacity and the post-earthquake repairability of the steel frame combined steel plate shear wall are remarkably improved. Meanwhile, the energy dissipation pieces, the beam connecting plates and the combined steel plate shear wall sequentially form a plurality of defensive lines under small earthquakes, medium earthquakes and large earthquakes, and the anti-seismic performance of the structure is remarkably improved.
本发明公开了一种内拱式钢框架‑组合钢板剪力墙及其安装方法,包括柱、梁和剪力墙,所述柱设置在剪力墙左右两端,梁设置在剪力墙上下两端,所述剪力墙包括蝶形板,所述蝶形板安装在同层相对布设的柱之间,蝶形板中央的前后两侧分别安装有耗能件,蝶形板与梁之间安装有梁连接板,所述梁连接板采用夹芯板结构。本发明能够利用内拱效应改善因钢板平面外屈曲引起的滞回曲线捏缩现象,并可将钢框架组合钢板剪力墙的塑性铰从钢框架梁转移至组合钢板剪力墙内部,显著提高钢框架组合钢板剪力墙的承载能力、耗能能力和震后可修复性。同时,耗能件、梁连接板、组合钢板剪力墙依次形成了小震、中震、大震下的多道防线,显著提高结构的抗震性能。
