摘　　要：在多孔蝴蝶形钢板剪力墙的蝴蝶杆腰宽比控制在0.4的前提下,有两种改变钢板墙开孔率的方法:改变蝴蝶杆的高度L和改变蝴蝶杆的排数m。采用有限元数值模拟,分析在低周往复荷载作用下,这两种改变开孔率的方法对钢板墙滞回性能、承载力和耗能性能的影响。分析结果表明:随着蝴蝶杆高度L和蝴蝶杆排数m的减小(即钢板墙的开孔率减小),钢板墙的承载力与耗能增加;当开孔率一定时,改变蝴蝶杆的排数m比改变蝴蝶杆的高度L对钢板墙的承载力和耗能变化影响更大。For the porous butterfly-shaped steel plate shear wall with the waist width ratio of the butterfly rod at 0.4,if the opening ratio of the steel plate wall needs changing,there are two ways which are to change the height of the butterfly-shaped short columns and to change the row number of the butterfly poles.The seismic performance of porous butterfly-shaped steel plate shear walls under the low cycle reciprocating loading is analyzed with the finite element numerical simulation,and the influence on the performances of hysteresis and energy dissipation are analyzed.The results show that with the decrease of the height of the butterfly-shaped short columns and the row number of butterfly poles(that is,the opening ratio of the steel plate wall decreases),the bearing capacity and energy consumption of the steel plate wall increase.When the opening ratio is fixed,changing the row number of butterfly poles has more influence on the bearing capacity and energy consumption of the steel plate wall than changing the height of the butterfly-shaped short columns.
