[摘要] 鋼框架—填充墻體系是鋼結(jié)構(gòu)住宅中最為重要的受力體系之一。而結(jié)構(gòu)設(shè)計時并未考慮填充墻對結(jié)構(gòu)整體抗側(cè)性能的貢獻(xiàn)。本文通過ABAQUS有限元軟件模擬鋼框架—填充復(fù)合板結(jié)構(gòu)在低周往復(fù)荷載作用下的情形，并與已有試驗數(shù)據(jù)對比，驗證模型的正確性。通過有限元結(jié)果和試驗數(shù)據(jù)分析，得到復(fù)合板對結(jié)構(gòu)整體抗側(cè)性能的貢獻(xiàn)，進(jìn)而模擬出鋼框架—填充墻結(jié)構(gòu)簡化計算模型，得到鋼框架—填充墻結(jié)構(gòu)的抗側(cè)剛度簡化計算公式，為理論分析及結(jié)構(gòu)設(shè)計提供依據(jù)。

Abstract: The steel frame filled wall system is one of the most important stress systems. The structure design does not consider the lateral performance of the filler wall on structures. In this article, by using ABAQUS software to simulate steel frame filled composite board structure under low cyclic loads situation, and compared with existing test data, validated the correctness of the model. By analyzing finite element results and test data to get the lateral performance of the composite plate on structures and simulate the simplified calculation model for the steel frame filled wall structure, got simplified calculation formula of the steel frame filled wall structure’s lateral stiffness, provided the basis for theoretical analysis and structure design.
Keywords: steel frame filled composite plate structure; finite element analysis; lateral performance; simplified formula
