摘要:

This paper proposes a new prefabricated concrete filled steel tube-bordered monolayer reinforced shear wall structure, which is composed of concrete filled steel tube borders and reinforced concrete wallboard. The shear wall can be assembled conveniently by connecting with the beams of the main frame via high-strength bolts, and it can resist horizontal earthquake forces with the frame. Six shear wall specimens were designed and tested under lateral cyclic loads. The effects of the axial compression ratio and rebar support on the seismic performance were analyzed. The test results indicated that the concrete filled steel tube borders and the concrete wallboard work well with each other. The peak load of each specimen increased with increasing axial compression ratio. With rebar support in the wallboard, the peak load, initial stiffness and energy dissipation capacity of the specimens increased. In addition, the deformation capacity of the proposed shear wall structure can meet the requirement of the elastic-plastic interstory drift ratio (1/100) of seismic design in practical engineering. A finite element method analysis was conducted, and the simulation results showed good agreement with the test results. Finally, based on the test and finite element simulation results, a calculation model of the normal section was proposed to predict the bearing capacity of the structures, which was verified by the small errors with calculation results.
