摘要
研究了可替换连梁保险丝腹板菱形孔洞参数对联肢剪力墙结构耗散能量的影响.在菱形尺寸不变情况下,对菱形孔不同倒角和半径的连梁保险丝模型进行低周往复加载有限元分析,得出如下结论:在开孔边界光滑情况下,保险丝耗能能力随菱形开洞倒角及半径的增加而增大,当倒角度数及半径增大到52°×46°×19mm×11mm时,保险丝耗能性能相对较好.
The effects of the parameters of the rhombus hole on the dissipative energy of the joint shear wall structure of the replaceable continuous beam fuse web are studied.In the case of unchanged diamond size,the finite element analysis is made on the diamond hole coupling model of different fuse fillets and radius of cyclic,and the conclusion is drawn as follows.In the case of open hole with smooth boundary,the fuse energy dissipation increases with the diamond shaped opening chamfer and radius,and when the chamfering degree and radius increased to 52°×46°×19 mm×11 mm,fuse has a relatively good performance of energy dissipation.
