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%。
The newly proposed soft mild steel damping wall is applied to the energy dissipation section of Y eccentric support. The mechanical properties of Y support steel frame under low cyclic reciprocating loads are simulated by ABAQUS software. Compared with the energy dissipation section of ordinary H beam, Y support steel frame for comparative analysis. The results show that the ductility is increased by 7% with respect to the Y-support steel frame using energy dissipation section of mild steel damping wall under the static load carrying capacity. The energy dissipation capacity of each Load level increased by 10%.
