摘要

为了提高普通密肋复合墙体的水平承载力和改善其抗震性能,在隐形框架里配置型钢形成型钢混凝土边框柱密肋复合墙体。应用ANSYS有限元软件对型钢混凝土边框柱密肋复合墙体进行非线性数值分析,根据不同的高宽比、轴压比和配钢率的计算结果,对该结构体系的延性及其破坏形态进行综合分析。分析结果表明,高宽比主要控制钢骨密肋复合墙体的破坏形态,轴压比对其结构的延性的影响最为显著。
In order to improve the horizontal load-bearing and seismic property of a common multi-ribbed composite wall,a shaped-steel-reinforced and multi-ribbed composite wall is constructed in a concealed frame.The nonlinear finite element analysis for the composite wall is completed by using ANSYS10.0.Based on the calculation results of models with the variable heightwidth ratio,axial compression ratio and steel percentage,the ductility and failure forms are analyzed comprehensively.The results indicate that the height-width ratio mainly controls the failure form of the wall,and the axial compression ratio affects its ductility obviously.
