Seismic performance of embedded optimized steel plate-reinforced concrete composite shear walls
摘要
Abstract
In order to improve the seismic performance of the traditional reinforced concrete shear wall,an embedded optimized steel plate-reinforced concrete composite shear wall was proposed.Considering the design principle of multi-dimensional loading and full stress criterion,an X-shaped optimized steel plate was arranged when the in-plane direction was the main seismic direction.When the out-of-plane direction was the main seismic direction,a triangular optimized steel plate was arranged.When the oblique direction became the main seismic direction,the X-shaped optimized steel plate and the triangular optimized steel plate were arranged at the same time.The hysteretic curves,skeleton curve,ductility,stiffness degradation and strain evolution of seven typical shear wall specimens were compared through cyclic loading test,and the damage assessment was carried out.The strain distributions of steel plates were compared by using finite element software to analyze the variable parameters.The results show that compared with the traditional reinforced concrete shear wall structure,the embedded optimized steel plate-reinforced concrete composite shear wall structure has higher bearing capacity,deformation capacity and bearing stiffness under multi-dimensional loading,which can effectively reduce the damage degree of the shear wall and improve its ultimate deformation capacity.Compared with the rectangular steel plate,the optimized steel plate proposed in this paper can achieve the full stress state at all loading angles,which has better economy and practicability.There are obvious differences in the seismic performance of shear walls under multi-dimensional loading,and special attention should be paid to their performance under out-of-plane loading and oblique loading conditions.关键词
