摘要:
为研究地震作用下竖向耗能接缝装配式剪力墙的受力性能与破坏机理,进行了X形金属阻尼器(XMD)的滞回性能试验,并对带XMD的竖向接缝装配式剪力墙进行了低周反复荷载数值分析,对比研究了试件的破坏形态、滞回性能、承载力、耗能能力和延性系数等.结果表明,XMD在循环荷载作用下表现出良好的滞回性能,阻尼器的刚度和承载力随着削弱段宽度的增加而增大.随着XMD数量的增加,试件预制墙板间的相对位移减小,试件的破坏形态逐渐由弯剪破坏向弯曲破坏转变.当XMD数量从0增加至18时,预制墙板间的相对位移减少约30.74%.竖向耗能接缝装配式剪力墙的刚度、承载力、延性和耗能能力随着XMD数量的增加而增大,其耗能值近似于预制墙板自身耗能值与阻尼器耗能值之和.
Abstract:
To investigate the mechanical behavior and the failure mechanism of precast shear walls with vertical energy-dissipating connection, the hysteretic tests of the X-shaped metal damper(XMD)and the numerical analysis of the precast shear wall with X-shaped metal dampers subjected to reversed cyclic loading were carried out. The failure mode, the hysteretic behavior, the bearing capacity, the energy-dissipating capacity and the ductility factor of specimens were comparatively studied. The results show that the XMD exhibits the good hysteretic behavior under cyclic loading. The stiffness and the bearing capacity of the XMD increase with the increase of the width of the weaken segment. With the increase of the number of the XMDs, the relative displacement between the wall panels of the specimens decreases, and the failure mode of the specimen gradually changes from bending-shear failure to bending failure. When the number of the XMDs on precast shear walls increases from 0 to 18, the relative displacement between the wall panels decreases by about 30.74%. The stiffness, the bearing capacity, the ductility, and the energy-dissipating capacity of the precast shear walls with vertical energy-dissipating connection increase with the increase of the number of the XMDs, and its energy-dissipating value of the specimen is approximately equal to the sum of those of the shear walls and the XMDs.
