Analysis of Seismic Fragility Curves of A Historical Building Made up of Masonry Structure

As India is a place of historical divine, here structure of 18 th century also exist in a safe and static condition without much failure in there stability. In this study we are selecting a historical monumental (mahal) building, collectings its dimensional data, material property, sectional details and strength to model the same structure of same aspects in Sap2000 and to Assign Non linear static analysis to check stability criteria and resistivity of an old structure. The fragility of a structures is defined as the conditional probability of failure at a given value of seismic response parameter as maximum acceleration, velocity displacement, spectral acceleration, effective acceleration Arias intensity, etc. Generally there are two ways of defining seismic fragilities, i.e. in terms of global ground motion parameter or in terms of local response parameter. Most frequently the objective of the fragility evaluation is to estimate the peak ground motion acceleration value for which the seismic response of a structure (system, component) exceeds the capacity resulting in failure. The estimation of the ground acceleration value could be performed on the base of calculations or based on experience data (the later could be from real earthquakes or dynamic tests). Because there are many sources of variability the structure (component) fragility is expressed usually by family of curves.
