Abstract

In order to study the failure characteristics and seismic performance of precast concrete shear walls, the basic failure processes and phenomena of six shear walls were introduced. The length of the reinforcing bar of the prefabricated shear wall specimens with three confinement anchors was 1 times that of the anchorage length of the steel bar. Through analysis and observation, the failure forms of three prefabricated concrete shear walls of YZ12, YZ16 and YZ20 were bending shear composite failure. Because of the effect of the spiral stirrup, the collapse phenomenon was not found in the concrete core area of the compression zone. At the end of the test, the vertical steel bars were yielded. The results show that the most lateral longitudinal bar of YZ12 was broken at the connection between the ground beam and the prefabricated shear wall specimens. In the late test of three contrast cast-in-situ shear walls, the concrete compression zone was completely crushed and the edge longitudinal reinforcement exposed and showed obvious deformation. Therefore, the binding method of constrained pulp anchorage bar is safe and effective.
