Abstract– In the present research, an explicit dynamic analysis is conducted on a typical multistorey
Steel Plate Shear Wall (SPSW) designed according to AISC requirements. The SPSW
model is subjected to a base earthquake acceleration record to simulate the time history response
of the structure. The analysis utilizes a finite element method involving both material and
geometric nonlinearities. The energy dissipation behavior and distribution of storey shear over
height of the model are investigated through time history response of the system. In addition, this
paper proposes a new definition of energy ductility, which can be used in the investigation of the
dynamic response of SPSWs. The ductility demand based on the proposed definition as well as
shear resistance contribution of the web plate and Vertical Boundary Elements (VBE) of SPSW
are evaluated.
Keywords– Shear wall, steel plate, dynamic response, transient, energy dissipation, energy ductility
