- 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.
