Abstract

In view of the current situation of box structures without supporting shear wall, this paper proposed a double-plate shear wall suitable for the new box structure system. Through low-cycle repeated load tests of five different structural forms of the walls, the influence of the improved wall rib size on the seismic performance, such as failure mode, hysteresis curve, skeleton curve, strength degradation, stiffness degradation and energy dissipation capacity of the wall, was studied. The results show that all the walls have good seismic performance, and different structural measures to improve the wall ribs can alleviate the damage degree of the wall to a certain extent. Adding transverse ribs is the most effective way to improve the seismic performance of the wall. The strain comparison curve shows that the steel bar and concrete can work together and have good deformation coordination performance.

Key words
