| 摘 要： | 利用大型通用有限元软件ANSYS,对单层和高层短肢剪力墙结构体系,从弹性到混凝土开裂直至破坏的全过程进行了仿真分析.揭示了单层单跨和高层连肢短肢剪力墙结构裂缝开展和破坏过程,分析了影响短肢剪力墙受力的各种因素:墙肢截面高厚比、混凝土强度等级、连梁跨高比、轴压比和结构层数等对短肢剪力墙承载能力和变形能力的影响.仿真试验结果表明:不同结构参数对短肢剪力墙弹塑性受力性能均会产生不同程度的影响,适当地调整设计参数可以优化结构的弹塑性性能.短肢剪力墙截面高厚比在6.5左右时,承载能力和变形能力较高;高层短肢剪力墙结构荷载-侧移曲线为弯剪型,连梁的屈服先于墙肢的屈服,属于强肢弱梁型结构.

| Abstract: | Simulative analysis on single and multi-storey coupled shot-leg shear wall is carried out using the general FEA program ANSYS,and its cracking and failure process is revealed.Some factors influencing the load-carrying and deformation capacity such as sectional depth-thickness ratio,concrete strength grade,span-depth ratio of couple beam,axial compression ratio and building stories are discussed.The result reveals that different factors may have different influence on the elasto-plastic property of short-leg shear wall system,and the appropriate selection of the design factors may improve its property.When the sectional depth-thickness ratio is 6.5 the load-carrying and deformation capacity are relatively high.The load-displacement curve of shot-leg shear wall is flexure-shear shaped,couple beam yield before the shear wall. |
