Many old damaged and undamaged building structures do not meet the criteria of modern seismic design codes. Such structures need to be seismically enhanced. The main objective of this paper is to validate the effectiveness of steel plate shear walls (SPSW) as upgradation tools for non-seismic undamaged steel structures. Several recent research works have recommended SPSW as effective lateral load resisting components for building structures. The upgradation is carried out considering a performance based probabilistic approach, wherein Incremental Dynamic Analysis (IDA) is used. The upgradation involves a static energy based scheme for the design of SPSW, to sustain a certain amount of interstory drift demand. The proposed procedure is tested on a 7-story steel framed building structure. The results lead to substantial drift reduction overall, showing the effectiveness of the SPSW; however, in case of some earthquakes, the drifts are above the selected target drift. In such cases, the ineffectiveness of SPSW in meeting the probabilistic target is assigned to not accounting for several uncertainties properly in the upgradation framework, and to the formation of unwanted plastic hinges in the columns bounding the SPSW, leading to the loss in their shear resisting capacity. Proper design of boundary elements encompassing the SPSW can improve the behavior of the upgraded structures substantially. On the whole, the proposed procedure is found to be effective for the upgradation of non-seismically designed steel frame structures to satisfy an inelastic drift based probabilistic performance criterion.
