Abstract: Plastic-hinge-supported walls can replace the bottom strengthening area of traditional RC shear walls and form a stable plastic energy dissipation zone at the bottom of the wall. By setting shear components that only bear horizontal shear and vertical load and bending components that only bear bending moment, a bending-shear-decoupling design is realized for shear walls. Based on the separation of bending and shear, the experimental study on the seismic performance of prefabricated plastic-hinge-supported walls considering the out-of-plane deformation is carried out. We introduce the quasi-static test of two 1/3 scale wall specimens, which used a concrete shear wall and a steel plate shear wall. The test results show that the connection mode of the prefabricated plastic-hinge-supported wall proposed in this paper is reasonable and effective, and that the wall specimen has good seismic performance even with the presence of out of plane deformation.
