【摘要】：为了研究密肋网格防屈曲构件对钢板剪力墙结构性能的影响,对设置防屈曲构件和不设置防屈曲构件的两榀三层钢板剪力墙结构进行了拟静力试验研究。对比分析两种结构的滞回性能,破坏模式,以及承载力、耗能和刚度等力学性能指标。研究表明:在不考虑肋条对内填板嵌固的基础上,需对密肋网格防屈曲钢板剪力墙肋板间距以及肋板刚度进行构造设计;相比于不设置防屈曲构件的钢板剪力墙,密肋网格防屈曲钢板剪力墙结构,避免了结构滞回环体的捏缩现象和墙板的整体呼吸效应,极大减弱了墙板的声响和震颤现象,降低了边框柱的破坏程度;墙板破坏为小区格内板件和边缘板件的局部屈曲,肋板未发生破坏;设置防屈曲构件结构的承载力和耗能量分别提高24%和20%,位移延性系数降低28%。
[Abstract]:In order to study the influence of anti-buckling members of multi-ribbed grids on the performance of steel plate shear wall structures, two three-story steel plate shear wall structures with and without anti-buckling elements were studied by pseudo-static test. The hysteretic performance, failure mode, bearing capacity, energy dissipation and stiffness of the two kinds of structures are compared and analyzed. The results show that, on the basis of non-consideration of the internal filling plate inlay, the structural design of the rib-plate spacing and stiffness of the multi-ribbed mesh anti-buckling steel plate shear wall should be carried out. Compared with the steel plate shear wall without flexure components, the multi-ribbed grid anti-buckling steel plate shear wall structure avoids the collapse phenomenon of the hysteretic body of the structure and the overall breathing effect of the wall board, and greatly weakens the sound and tremor phenomenon of the wall board. The failure degree of the side-frame column is reduced; The failure of the wall panel is the local buckling of the inner panel and the edge plate, and the rib plate is not destroyed. The bearing capacity and energy consumption of the structure with anti-buckling elements are increased by 24% and 20% respectively, and the displacement ductility coefficient is reduced by 28%.
