Abstract

Based on the studies over the recent decades, STEEL PLATE SHEAR WALLs, SPSWs, have been introduced as appropriate seismic load resisting systems, which have come to be used in structural design and in retrofitting of existing buildings with different configurations, both stiffened and un-stiffened. The few investigations carried out on SPSWs have shown that stiffening of a thin STEEL PLATE SHEAR WALL with the conventional horizontal and vertical stiffeners improves its non-linear behaviour.However, application of conventional stiffeners, commonly used for precluding incidence of shear elastic buckling in infill plates, is time-consuming and imposes high-fabrication costs. This study was, therefore, carried out to investigate the stiffening of SPSWs with DIAGONAL STIFFENERS and their non-linear behaviour. The theoretical formulas validated against analytical results are presented that are used to estimate the SHEAR STRENGTH capacity of the system and to size the DIAGONAL STIFFENERS. The results show that DIAGONAL STIFFENERS reduced the effective lengths of buckling in the inclined infill steel plate strips and, consequently, increased the elastic SHEAR STRENGTH of the infill steel plate as well as the ultimate shear capacity of the system when compared to un-stiffened steel shear walls. Good agreement is also observed between theoretical and analytical results.
