冻融环境作用下低矮RC剪力墙抗震性能试验研究OA北大核心CSCDCSTPCD
Experimental Study on the Seismic Behaviors of Squat RC Shear Walls under Action of Freeze-thaw Cycle
采用人工气候快速冻融试验方法,对4个实际剪跨比为1.14的低矮RC剪力墙试件进行冻融试验,进而对其进行低周反复加载试验,研究低矮RC剪力墙经不同冻融循环作用后其抗震性能的衰减规律.以承载力、延性系数、塑性转角、强度衰减、刚度退化和累积滞回耗能等指标为参数,探讨冻融循环次数对低矮RC剪力墙抗震性能的影响.结果表明:暗柱和墙体分布钢筋可以约束冻胀裂缝的开展,延缓冻融循环作用对墙体造成的破坏;冻融循环作用会引起低矮RC剪力墙的破坏模式由弯曲为主的弯剪破…查看全部>>
Four RC shear wall specimens with a shear span ratio of 1.14 were subjected to rapid action of freeze-thaw cycles in artificial climate room,and then the quasi-static tests were carried out to study the deterioration of seismic behaviors of the shear walls under different action of freeze-thaw cycle.Six performance indicators,such as load carrying capacity,ductility,plastic rotation,strength degradation,stiffness degradation,and cumulative hysteretic e…查看全部>>
