为研究加劲肋和竖向荷载对钢板剪力墙受力性能的影响,分别对1榀和2榀竖向加劲钢板剪力墙进行推覆和往复试验,其中往复试验中以有限竖向荷载为控制变量。通过考察剪力墙板变形性能以及竖向加劲肋的整体屈曲及局部屈曲,得到试件的推覆曲线和荷载-位移滞回曲线,并基于试验结果分析试件承载力、抗侧刚度和耗能能力等力学性能。结果表明:有限竖向荷载对竖向加劲钢板剪力墙的屈曲荷载、抗侧刚度和耗能性能影响较大,对屈服荷载和极限承载力影响较小;并给出了竖向加劲肋和侧边加劲肋的门槛刚度系数值。
In order to study the effect of stiffeners and vertical loads on the mechanical properties of steel plate shear walls, 1 榀 and 2 榀 vertical stiffened steel plate shear walls were subjected to push-back and reciprocating tests respectively. The reciprocating tests were performed with limited vertical load as Control variables. Through examining the deformation performance of shear wall panels and the integral buckling and local buckling of the vertical stiffeners, the pushover curve and load-displacement hysteresis curve of the specimen are obtained. Based on the test results, the bearing capacity, Ability to wait for mechanical properties. The results show that the limited vertical load has a great influence on the buckling load, lateral stiffness and energy dissipation performance of the vertically stiffened steel plate shear wall, and has little effect on the yield and ultimate bearing capacity. The vertical stiffeners and Side stiffener threshold stiffness coefficient value.
