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。 Four high strength concrete shear wall specimens (with wall and wall in the vertical slit wall) under low cyclic loading test, study the number and length of vertical slits (ie, shear-span ratio of the wall column) On the shear wall stiffness, bearing capacity, ductility, energy consumption, damage morphology and other seismic performance. The results show that when the vertical slits are set in the shear wall, the ductility, plastic deformation and energy dissipation ability of the slits can be drastically improved under the condition of little change in the elastic rigidity and bearing capacity.
