| 摘 要： | 分析钢框架结构体系1∶2双层单跨钢框架-填充墙模型的抗震试验结果,对比该试件实体建模的有限元分析结果,提出可用于模拟钢框架和填充墙共同抗侧力机制的框架-墙体三支杆简化力学模型,并按照该受力模型进行有限元建模和水平荷载作用下的结构位移、刚度及内力分析.计算结果表明,与钢框架-填充墙原始模型实体建模的计算结果相比,钢框架-填充墙三支杆模型计算结果与试验结果更加吻合,验证了这一简化计算方法的合理性和实用性.

| Abstract: | Compared with seismic test results and finite element analysis(FEA) results by original structural modeling of a 1∶2-scale one-span two-storey masonry-infilled steel frame specimen,three-strut model for masonry-infilled steel frame structure is presented here.This mechanical model can be applied to simulating the lateral load resistance mechanism of steel frames working together with masonry infill.The FEA results of three-strut model are more consistent with the test results than that of the original frame-wall solid model in displacements,rigidity and internal forces.It proves the feasibility and practicability of this simplified analyzing method for masonry-infilled steel frames. |
