Seismic Behaviour of Steel Plate Shear Walls with Door and Window Sized Openings
Steel Plate Shear Wall (SPSW) has widely been accepted as an effective lateral load resisting system for resisting wind and earthquake loads. Often, SPSWs need to accommodate large door or window size openings in the infill plates, such as when SPSWs are used in the building central cores around the elevators. Current AISC design standard recommends the use of horizontal and vertical local boundary elements (LBE), in the form of stiffeners, around these large rectangular openings to anchor the tension field developed in the infill plate. Research on SPSW with stiffened door and window sized openings is very limited. This paper presents seismic performance of SPSWs with door and window sized openings in the infill plate. A nonlinear FE model is developed in ABAQUS to study behavior of SPSWs with door and window sized openings. Two multi-storey (3- and 5-storey) SPSWs with standard door and window sized openings are designed following the guidelines of current AISC design guide 20. Seismic behavior of the selected SPSWs is carried out by conducting a series of time history analysis using a suite of 8 ground motions compatible with the design response spectrum of Vancouver, Canada. Effectiveness of the designed stiffeners to limit both in-plane and out-of-plane deformations around the rectangular openings is examined from the seismic analysis. The paper also investigates whether the use of the local boundary elements (stiffeners) around the rectangular openings alters the recommended yielding sequence of the SPSW system.
