摘要:
Precast concrete hollow shear wall structure is a new type prefabricated structure. In order to study the seismic performance of the precast concrete shear wall, the integrity of adjacent walls at same level, resisting shear through indirectly spliced horizontal reinforcement, and the grouted boundary element, quasi - static tests were conducted on six shear wall specimens with axial load ratio of 0.3 and aspect ratio between 1.61 and 2.42. The test results show that the failure mode of the specimens is flexure-compression failure, thus the design goal of strong shear and weak bending is reached, and the horizontal reinforcement can resist the shear force effectively. The relationship curve between the force and the displacement is full, and ultimate drift ratios are between 1/72 and 1/38. The bearing capacity calculation of hollow panel under eccentric compression can refer to the cast-in-situ shear walls. The cracking width of vertical joint between adjacent walls at the same floor is small, and the walls on both sides of joint slip little along vertical direction, and the diagonal crack is continuous in the vertical joint. The shear wall can become integrity through direct connection or cast-in-situ vertical joint. The seismic performance of concrete hollow panels with grouted boundary element can meet the requirement of current codes. © 2019, Editorial Office of China Civil Engineering Journal.
