[摘要]将最新提出的新型软钢阻尼墙应用到Y偏心支撑的耗能段,通过ABAQUS软件对Y支撑钢框架在低周往复荷载作用下的力学性能进行模拟,并与采用普通H型钢耗能段的Y支撑钢框架进行对比分析。结果表明,在保证静力承载能力下,采用软钢阻尼墙耗能段的Y支撑钢框架相对于采用普通H型钢耗能段的Y支撑钢框架,延性提高7%,耗能能力在每个加载级别提高10%。

Abstract:The developed new type of mild steel damping wall was applied to the Y-eccentric braced link beam. The mechanical properties of the Y-typed steel frame under low cyclic reciprocating load were simulated by ABAQUS software, and the results were analyzed and compared with those of Y-typed braced steel frame with ordinary H-typed steel link beam. The results show that, ensuring the static load capacity, the Y-typed braced steel frame with mild steel damping wall link beam has 7% higher ductility than the Y-typed braced steel frame with ordinary H-typed steel link beam, and the energy consumption increases by 10% at the each loading level.
Keywords:mild steel damping wall; Y-eccentric brace; link beam; hysteretic analysis
