Presently, the Indian codes utilize a force based methodology for seismic design of structures. This approach has several shortcomings which has led to the development of alternative design methodologies. The performance based approach aims at developing designs that meet certain performance criteria for a specified hazard level. This paper introduces a displacement based approach based on Indian conditions to obtain earthquake resistant design for RC framed structures. The effectiveness of direct displacement based design (DDBD) with respect to Indian code based design is compared. Three sets of RC frames of 3, 5 and 8 storey are designed according to latest Indian codes and DDBD approach. Pushover analysis of the structure is then carried out to evaluate the performance of each design methodology. It is observed that the base shear calculated by DDBD is significantly lesser than calculated according to IS 1893:2002. The DDBD approach results in a more economical design. Further, as the height of structure increases the force based method becomes more conservative and uneconomical.
