利用ANSYS对七个十字型钢筋混凝土短肢剪力墙进行单调荷载作用下的弹塑性分析,比较了剪力墙截面高厚比变化时,剪力墙的承载能力、刚度和延性变化情况,分析结果表明,随高厚比的提高,结构的承载力有所提高,而延性先增加后降低,结构设计中应充分考虑该因素的影响.当剪力墙高厚比为6.6时,承载能力及变形能力均较好,屈服荷载与极限荷载提高显著,延性系数达到最大,为实际工程的截面设计提供了有意义的依据.

The elastic-plasticity analysis on seven specimens of cross-section reinforced-concrete short-limb shear wall under monotonic loading is performed by means of the nonlinear finite element analysis with the software ANSYS, which compares the changes in the shear carrying capacity, rigidity and ductility as the wall depth-thickness ratio U changes. The analysis results show that with the increased depth-thickness ratio U the carrying capacity of the structure has increased, while the ductility first increases and then decreases. These factors should be fully taken into consideration in structural design. When the U is about 6.6, the carrying capacity and deformation capacity of this shape of shear wall are better in performances, and the yield load and ultimate load are increased significantly. Also the ductility factor is maximized, which provides a meaningful basis for practical section engineering design.
