In this study the influence of location of lateral force resisting systems on the response reduction factor (R), ductility and plastic hinge status at performance point of the RC buildings were studded. The present paper made an attempt to study 4 types of 10 storey RC frame structure with different positions of shear wall on the symmetrical floor plans. Nonlinear pushover analysis has been performed using ETABS software in according with IS1893-2002. The actual values required for determination of response reduction factor (R), ductility and performance of the building are work out on the basis of pushover curve which is a plot of base shear verses roof displacement and pushover curve gives the actual capacity of the structure in the nonlinear rang. The results show that due to transfer the shear wall to the inner core, response reduction factors (R) and ductility reduce, but the number of plastic hinges beyond collapse increase. So it is essential to consider the effect of shear wall shifting for the seismic evaluation of RC buildings.
