基于纤维模型法,编制双钢板混凝土组合剪力墙(以下简称组合剪力墙)的双向压弯非线性分析程序,通过与已有试验结果、有限元计算结果的对比,验证分析程序的准确性。基于分析程序重点对组合剪力墙的双向压弯承载力进行数值计算,计算结果表明:面外弯矩的存在将显著降低组合剪力墙的面内承载能力,当组合剪力墙处于双向压弯受力状态时,完全按照面内承载进行设计将严重高估构件的承载能力。同时,利用分析程序对组合剪力墙进行参数分析,讨论荷载偏心角、荷载偏心距、混凝土强度和含钢率对组合剪力墙承载力的影响。
Based on the fiber model method, two-way bending nonlinear analysis program of double-steel-concrete composite shear wall (hereinafter referred to as combined shear wall) is established. By comparing with the existing experimental results and finite element calculation results, the accuracy of the program is verified . Based on the analysis program, the bearing capacity of the composite shear wall is calculated. The calculation results show that the existence of out-of-plane bending moment will significantly reduce the in-plane bearing capacity of the composite shear wall. When the combined shear wall is in bidirectional compression Bending stress state, designed in full accordance with the plane bearing will seriously overestimate the load carrying capacity of the component. At the same time, the analysis program is used to analyze the parameters of the combined shear wall, and the influences of load eccentricity, load eccentricity, concrete strength and steel content on the bearing capacity of the combined shear wall are discussed.
