[摘要]  钢框架—填充墙体系是钢结构住宅中最为重要的受力体系之一。而结构设计时并未考虑填充墙对结构整体抗侧性能的贡献。本文通过ABAQUS有限元软件模拟钢框架—填充复合板结构在低周往复荷载作用下的情形，并与已有试验数据对比，验证模型的正确性。通过有限元结果和试验数据分析，得到复合板对结构整体抗侧性能的贡献，进而模拟出钢框架—填充墙结构简化计算模型，得到钢框架—填充墙结构的抗侧刚度简化计算公式，为理论分析及结构设计提供依据。

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
