ABSTRACT
Earthquake scan cause damage to any type of man-made structure to varying degrees. Mitigation against seismic damages requires a scientific estimation of the hazards and their impact on structural systems. As structural systems are pushed beyond their linear limit of material and geometry, seismic hazard estimation becomes complex. Seismic hazard in the form of fragility curves can be developed using linear dynamic analysis and/or non-linear static analysis. In this study, a G+4 story Reinforced Concrete (RC) building with a moment resisting frame was considered in a high seismic zone. Fragility curves for a RC building for maximum story drift were developed using linear dynamic analysis with an emblem of earthquake ground motion. Fragility curves were also developed using non-linear static analysis based on FEMA 440 for maximum story drift. A comparative study between guidelines of ATC 40 to modified guidelines of FEMA 440 was also attempted. It was found that despite RC buildings being designed for seismic loading as per IS 1893 (Part 1): 2002, they were deficient with an increase in PGA values for a set of ground motions.
