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。
Steel frame - infill wall system is one of the most important stress system in steel house. The structural design did not take into account the contribution of infill walls to the structure as a whole. In this paper, ABAQUS finite element software is used to simulate the steel frame-filled composite plate under low cyclic reciprocating loads. Compared with the existing experimental data, the correctness of the model is verified. Through the finite element analysis and experimental data analysis, the contribution of the composite plate to the overall anti-side performance of the structure is obtained, and then a simplified calculation model of the steel frame-filled wall structure is simulated. The simplified formula of the anti-side rigidity of the steel frame- Theoretical analysis and structural design provide the basis.
