Experimental Study of Bearing Capacity of Steel Frame with Portal Steel Plate Shear Wall Member

Abstract

The steel frame with portal steel plate shear wall unit presented here is a new steel structure by assembling the portal steel plate shear wall into the steel frame through bolt connection. For study of shear resistance and bearing capacity of the structure, it is necessary to conduct experimental research. Three frame specimens are made here, and two geometric shapes and the case of setting stiffeners and not setting stiffeners are considered respectively. The concentrated lateral load is applied in the test and displacements and strain were measured. The results show that the setting of the shear wall element has an obvious effect on improving the lateral stiffness of the steel frame, and the failure also shows obvious plastic deformation characteristics. It is also seen that the connection has no evident failure or deformation, which means the connection construction is effective.
