［摘要］將最新提出的新型軟鋼阻尼墻應(yīng)用到Y(jié)偏心支撐的耗能段，通過(guò)ABAQUS軟件對(duì)Y支撐鋼框架在低周往復(fù)荷載作用下的力學(xué)性能進(jìn)行模擬，并與采用普通H型鋼耗能段的Y支撐鋼框架進(jìn)行對(duì)比分析。結(jié)果表明，在保證靜力承載能力下，采用軟鋼阻尼墻耗能段的Y支撐鋼框架相對(duì)于采用普通H型鋼耗能段的Y支撐鋼框架,延性提高7%，耗能能力在每個(gè)加載級(jí)別提高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
