To Develop Fragility Curve For Rc Building Under Seismic Load With Plan And Vertical Irregularities

  Kantliwala Kartik,  Aditya Bhatt,  Yati Tank

The significant damage has been observed repeatedly to structures with structural irregularities in their plans during many past earthquakes, great research has been undertaken to assess their seismic vulnerability. While most of the previous studies used simple conceptual representations such as one-dimensional or two-dimensional templates in the study of fragility of abnormal design systems. A HAZUZ methodology is provided here for deriving fragility curves for systems with design abnormalities. A spatial damage index is formulated and used as a damage characterization measure to characterize the damage state of irregular structures. The procedure is illustrated through a reference derivation of fragility curves for an irregular RC building. Fragility analysis is used to develop the different damage grades based on HAZUS methodology. Damage probability matrices for quality point as per ATC-40 were developed to assess the damage condition for each hazard level
