Abstract

Abstract

In the double-steel-plate composite shear wall of the cistern in a nuclear power plant reactor， stainless steel plates are usually installed on the surface of low-alloy steel to prevent steel plate corrosion. In order to implement the modular design for structural anti-corrosion， a stainless steel-concrete-normal steel sandwich composite shear wall was proposed， and quasi-static loading tests were conducted on three 1∶5 scale specimens in the plane. The failure modes， hysteretic curves， skeleton curves， stiffness degradation， ductility， and energy consumption of the shear wall were obtained. The effects of steel plate material， equal-thickness design， and equal-strength design on the seismic performance of shear wall were analyzed. The results showed that the stainless steel-concrete-normal steel sandwich composite shear wall exhibited good seismic performance， and its bearing capacity and lateral stiffness could be effectively improved with the increase of steel plate strength and steel ratio. The final failure mode of each specimen was bending failure. Based on the test results， the calculation model of the shear wall was established， and the simplified calculation formula for the compressive bending capacity was proposed. The feasibility of the formula was verified by comparison with experimental results.
