Experimental Research on Seismic Performance of Core Grouted Concrete Prefabricated Shear Walls with Vertical Mixed Reinforcement on Wall

In order to study the seismic performance of core grouted congruent concrete prefabricated shear walls with vertical mixed reinforcement on the wall, 1 cast-in-place concrete shear wall specimen and 2 core grouted congruent concrete prefabricated shear walls were designed and full-scale fabricated. The walls of the two prefabricated specimens adopted the method of vertical symmetrical reinforcement and vertical mixed reinforcement respectively, quasi-static tests were conducted according to the axial compression ratio of 0.3. The test results showed that the failure patterns of the shear wall specimens with mixed reinforcement and the shear wall specimens with symmetrical reinforcement were similar, and both had compression and bending failure; there was no obvious slip phenomenon between the prefabricated member and the core grouted concrete; the seismic performance of shear wall specimens with symmetrical reinforcement was slightly higher than that of shear wall specimens with mixed reinforcement; the core grouted congruent concrete prefabricated shear walls with vertical mixed reinforcement on the wall could meet the requirements of Code for Seismic Design of Buildings (GB 50011—2010).
