During the recent decades, many researches have been carried out on steel plate shear walls, SPSWs and accordingly, they have been classified as a reliable lateral load resisting system in the high seismic risk zones. This has given rise to increase of attentions to SPSWs as a new and economical system in structural design of buildings and even retrofitting of existing structures. Since different philosophies have been elaborated to explain and improve nonlinear behavior of SPSWs, various configurations are deemed in the design and construction of SPSWs as stiffened, un-stiffened, with holes, with simple or rigid frames, etc. Where, the stiffened approach employs stiffeners to prevent the infill steel plate fully or partially from elastic out-of-plane buckling. The un-stiffened approach relies mainly on post-buckling strength of infill steel plate ascribed to tension field action development in the plate. Also, application of holes in the infill plates is sometimes considered for passing utilities, architectural purposes, and/or special structural reasons. In addition, the type of peripheral frames affects nonlinear responses of the steel shear walls. This variety of the theories and applications might face structural designers with the difficulty of selection of an appropriate system in the design. Hence, in this study, seismic behaviors and structural characteristics of steel shear walls with different construction details are investigated based on the experimental and analytical results. Some aspects of advantages and areas of concerns of each type of steel plate shear walls are briefly reviewed and discussed, and some considerations are resulted and presented.
