钢筋混凝土短肢剪力墙抗震性能试验研究

Experimental research on seismic performance of R C short-limb shear wall

通过6片12单层短肢墙试体的低周反复荷载试验,研究了在低周反复荷载作用下钢筋混凝土短肢剪力墙的整体工作性能、破坏形态及滞回特性。结果表明试件的最终破坏均是由连梁失效引起的,连梁是短肢剪力墙结构的薄弱环节,因此,连梁的混凝土强度不应低于墙肢的混凝土强度,以免连梁出现粘结破坏;有翼墙的短肢剪力墙试体其延性系数都达到了3.5以上,其耗能能力较无翼墙短肢墙好。

A experimental research on the seismic behaviors of 6 reinforced short-limbed shear walls with one-second-scale has been made. The test results show that the final damage of the samples all are caused by the connecting beam failure, which is the weak region of the reinforced short-limbed shear wall, so the concrete strength of inner beam must be higher than that of wall, in order to avoid the bonding damage. The ductility factor of the reinforced short-limbed wall with wing is greater than 3.5, the dissipative energy ability of the wall with wing is superior to that of wall without wing.
