Most of the constructions in hilly regions are constrained by local topography which results in the adoption of either a step back or step back &set back configuration. Due to this the structure is irregular by virtue of varying column heights leading to torsion and increased shear during seismic ground motion. The dynamic analysis is carried out using response spectrum method to the step back and step back & set back building frames. The dynamic response i.e. fundamental time period, storey displacement & drift, and base shear action induced in columns have been studied for buildings of different heights. These results show that the performance of step back & set back building frames are more suitable in comparison with step back building frames. But after considering bracings to the step back building frames, a better performance can be observed when compared with step back & set back building frames. In the present study the effect bracings in high rise RC structures sited in different types of earthquake zones (Z-II &V) and type of soils(S-II) using ETABS 2013 is done.
