【摘要】 钢框架内填钢筋混凝土剪力墙(SRCW)结构是由钢框架和钢筋混凝土剪力墙通过抗剪连接件组合而形成的新颖的结构体系,具有能承担较大水平剪力的特点,是一种较为经济的抗侧力体系。基于ABAQUS建立了SRCW有限元模型,并对其进行了单调水平荷载作用下的弹塑性分析,研究了各组件的工作机理和受力特征;分析了墙板高宽比、内填墙厚度、内填墙水平分布钢筋配筋率、内填墙混凝土强度等级变化对SRCW内填墙板受力性能、抗剪承载力及延性的影响。根据48个SRCW算例的有限元模拟结果,按统计方法提出了SRCW内填钢筋混凝土墙板抗剪承载力计算公式。更多还原

【Abstract】 The steel frame filled reinforced concrete shear wall(SRCW) is a new structure system composed of a steel frame and a reinforced concrete shear wall by shear connectors, which is an economical system to resist lat-eral force and characteristic of bearing the large horizontal shear force. In this paper, based on the ABAQUS software, the finite element model of SRCW is established, and the elastic-plastic analysis of SRCW under the monotonic horizontal load is performed to study the cooperative working mechanism and the shear bearing capac-ity of the components in the SRCW; the effects of design parameters such as the height to width ratio and the thickness of the infill wall, the rates of the horizontal reinforcing bars and the concrete strength of the infill wall on the SRCW behavior are analyzed. Based on the finite element simulation results of 48 SRCW specimens, the formulas to calculate the ultimate shear capacity of the reinforced concrete wall in the SRCW are proposed.更多还原
