屈曲约束钢板墙-钢筋混凝土框架结构滞回性能试验研究
Experimental study on hysteretic performance of reinforced concrete frame with buckling restrained steel plate shear wall
摘要
Abstract
In order to improve the seismic performance of reinforced concrete frame structures,the buckling restrained steel plate shear wall (BRSPSW) is used as lateral load resisting and energy dissipation component to form a new type of hybrid structure. The hysteretic performance of reinforced concrete frame with BRSPSW was studied by cyclic loading test and finite element simulation of two two-storey and one-bay specimens in terms of the loading process, failure mode,energy dissipation capacity,stiffness degradation and capacity degradation,etc. The research results indicate that reinforced concrete frame with BRSPSW has excellent seismic performance. BRSPSW greatly enhances the lateral stiffness,yield capacity,energy dissipation capacity,ductility and redundancy of reinforced concrete frame structure. The energy dissipation coefficient and ductility coefficient of specimens are about 2.0 and 10.0,which are far greater than those of reinforced concrete frame structure. Furthermore,the hysteretic model of BRSPSW is proposed in order to simplify the finite element analysis. Comparison with the test results indicates that the hysteretic model can simulate the loading behavior of the test specimen with reasonable accuracy,and can be used in the nonlinear dynamic elasto-plastic analyses of this kind of structures.关键词
