This article presents a study on the seismic performance and torsional sensitivity of RC shearwall buildings designed using the Equivalent Static Load (ESL) method for seismic design as provided inNBCC 2005. Three Reinforced Concrete (RC) buildings of four, eight and sixteen storey heights aredesigned and their seismic performance is studied. The performance parameters such as the demand tocapacity ratios for storey drift, plastic rotation, and storey shear are extracted from the results of theinelastic dynamic analysis. The statistical values including mean plus standard deviation of the demand tocapacity ratios are found to be well below the acceptable limits, while the shear in wall, exceeds the limitin all cases. Also, none of the buildings are torsionally sensitive within the code specified range of masseccentricity for which ESL method is applicable. The changes in the dynamic response due to the changein mass eccentricity are very small and almost proportional. Also, while results for the four and eightstorey buildings are not very sensitive to the method of scaling of the ground motion records, for thesixteen storey building, it is not so.
