For the past few decades global attention and interest has grown in the application of Ductile Steel Plate Walls (DSPW) for building lateral load resisting systems. Advantages of using DSPWs in a building as lateral force resisting system compromise stable hysteretic characteristics, high plastic energy absorption capacity and enhanced stiffness, strength and ductility. A significant number of experimental and analytical studies have been carried out to establish analysis and design methods for such lateral resisting systems, however, there is still a need for a general analysis and design methodology that not only accounts for the interaction of the plates and the framing system but also can be used to define the yield and ultimate resistance capacity of the DSPW in bending and shear combination. In this paper an analytical model of the DSPW that characterizes the structural capacity in the shear and bending interaction is presented and discussed. This proposed model provides a good understanding of how the different components of the system interact, and is able to properly represent the system's overall hysteretic characteristics. The paper also contributes to better understand the structural capacity of the DPSW and of the shear and bending interaction. The simplicity of the method permits it to be readily incorporated in practical non-linear dynamic analyses of buildings with DSPWs. To demonstrate the effectiveness of the proposed model, its predicted response is compared with results from experimental studies performed by various researchers.
