The main objective of the present study is to develop the fragility curves for the open ground storey buildings designed as per the modification factors suggested by the different international codal provisions and compare the relative performance on the probabilistic basis by developing the fragility curves. For the development of the fragility curves the nonlinear static analysis method is adopted here. The building model considered is having 10 storeys and 6 bays in both the directions and it is assumed to be situated in Zone V. The building is symmetrical in plan. So, only plane frame model can be considered for the representation of the whole building. The building is first designed in the STAAD. The Ground storey columns are designed according to the modification factors suggested by the different codes such as 1 and 2.5 (Indian), 3 (Bulgarian), 2.1 (Israel), 4.68 (Euro code) and approach suggested by Kaushik et. al (2009).These building frames are modeled in SAP. The capacity curve of the building is obtained from the non linear static analysis and the capacity curve control points of the building (yield and ultimate capacity control points) are obtained. From this control points the damage state median values are identified and fragility curves are developed for each damage states showing the cumulative probability of reaching or exceeding each damage state at given value of spectral displacement.
