The compliance of wall sections, designed as per the current Indian Standard, with the capacity design philosophy is investigated. For this, the material characteristics during overstrength conditions are used for concrete and steel. The overstrength axial force-bending moment interaction curves are used to determine the flexural plastic hinge based overstrength shear demand that is compared with the design shear capacity. Structural walls of multistoreyedframed buildings, designed as per the Indian Standard, are analysed to identify the possible modes of shear failure during flexural overstrength conditions. The top storeys of all the buildings and some storeys of the midrise buildings show vulnerability to shear failure. However no particular trend in the exceedance of shear demand over the design shear force is observed.
