Moment Resisting RC Frames in multi storey buildings predominantly make use of rectangular column system and they are widely practiced and globally accepted as default support system. Because of the availability of varieties of software for standard designs and ease of construction, rectangular columns are widely practiced in construction industries. The specially shaped columns, i.e., L,T and + shaped if strategically positioned at corner, peripheral and intermediate position respectively in a multi storey building frame, it would not only promise better structural response but will be more useful to articulately manage the floor space due to its special shape. Hence to verify the structural performance of moment resisting RC frames at different heights with these L, T and + shaped columns, an attempt is made in this work to model G+3, G+7 and G+13 storey SMRF in ETABS environment. Comparing the results for the similar frames with rectangular column as supporting system. A seismic analysis is performed on all these frames by response spectrum method by using built-in library of specially shaped columns and the results for storey drift, natural frequency and storey displacement for all these different height frames are acquired. The results obtained are depicted in this work with a comparison of SMRF with rectangular columns and for all these parameters, comparison is depicted in graphical and tabular form which shows clear advantage of use of specially shaped columns, to resist seismic performance of multi storey RC frame.
