Seismic Performance Analysis Of Openslotted Steel Plate Shear Wall

In recent years,due to the frequent occurrence of earthquakes,the national economic development and the safety of people's lives are threatened.Therefore,people pay more and more attention to the seismic performance of building structures.As a new type of lateral force resisting member,slit steel plate shear wall has been widely concerned.At present,there are few studies on the seismic performance of slit steel plate shear walls.A large amount of research is aimed at the mechanical properties of slit shear walls under static load,and the research on the open slotted steel plate shear walls has been paid more attention in recent years.In this paper,the Ansys finite element software is used to model the open slit steel plate shear wall and the frame.The hysteretic curve,skeleton curve,key performance index and failure form of the structure are analyzed.The results are consistent with the test results,and the rationality of the modeling is confirmed.The finite element method is used to analyze the factors affecting the hysteretic behavior of the open slit steel plate shear wall,including the height to thickness ratio of the inner fill plate,the stiffening stiffness of the stiffened rib,the ratio of the width of the slit between the joints and the slotting rate.Combining the finite element simulation with the theoretical analysis,the influence of the high thickness ratio of the filling plate to the seismic performance of the structure is smaller.It is suggested that the stiffness of the stiffener B at the edge of the filling plate is about 18.36,the ratio of the height to width of the wall limbs between the joints is about 6,and the slotting rate is about 0.41.It will provide a reference for the future research on the seismic performance and practical engineering application of the slotted steel plate shear wall.
