Cyclic Test of Steel Plate Shear Wall Designed by PFI Method
In this paper, Plate Frame Interaction (PFI) developed by other researches for modeling Steel Plate Shear Wall (SPSW) is applied for designing a half-scale, single bay and one story SPSW. After designing of SPSW, one specimen is constructed accordingly. In order to determine the mechanical properties of steel, coupon test is performed; and then again theoretical relations based on PFI is re-checked. In this study, gravity loads are neglected and only seismic resistance of SPSW is considered. With cyclic lateral loading as quasi-static load, according to Acceptance Criteria for Cyclic Racking Shear Tests For Metal-Sheathed Shear Walls with Steel Framing (AC154) and obtaining its hysteretic loops, force displacement diagram of the specimen is determined. Comparison of theoretical and experimental results shows that ultimate strength of SPSW based on theoretical analysis is lower than that of experimental analysis. By the way, due to large deformation of beam during the applied loading, it is proposed that plastic moment of beam be get higher, rather than that of proposed quantity. However, through increasing of beam and column rigidity and attention to weak girder- strong column theory, it is estimated that ultimate strength, ductility and energy dissipation of steel shear wall will significantly improve.
