摘要
通过四片高强混凝土剪力墙试件 (有整体墙和墙板中开竖缝墙 )在低周反复荷载作用下的试验 ,研究开竖缝数量及长度 (即墙板柱的剪跨比 )对剪力墙的刚度、承载力、延性、耗能、破坏形态等抗震性能的影响。结果表明 ,在剪力墙板中合理地设置竖缝 ,可使其弹性刚度、承载力变化不大的情况下 ,较大幅度地提高它的延性、塑性变形和耗能能力。
Based on the experimental study of 4 high strength concrete(HSC) shear walls subjected to cyclic loading, this paper analyzes the effects of the amount and length of the vertical seams on the seismic behavior of the shear wall,including rigidity, shear bearing capacity, ductility, energy dissipating capacity, failure modes etc, The experimental results show that some vertical seams being set up reasonably in normal HSC shear walls can greatly improve the wall's ductility, ultimate deformation and energy dissipating capacity and only reduce the elastic stiffness and shear bearing capacity of the HSC shear walls with vertical seams a little.
