Hence in seismic prone areas earthquake risk assessment of heritage structures becomes even more necessary. A systematic approach is used for this purpose. This approach is based on the estimation of expected number of earthquakes at each source with the help of Gutenberg-Richter relation and time-dependent hazard model and the estimation of structural damage during each of these events. The ground motion at the site under consideration during a particular event may be characterized in the form of the Power spectral density function (PSDF). To account for the non-linear behavior of structure, stochastic linearization techniques may be conveniently used to find the equivalent linear system properties in case of SDOF system. Damage can be quantified numerically by making use of damage indices (DI). A case study has been carried out for illustrating the proposed model, and it has been shown how this may be used to determine the design force levels for maximum allowable damage at the end of the design life. For the present study Earthquake Risk Assessment of Qutb Minar and India Gate situated in Delhi is done. The risk computed can be used to arrive at the present day strength of the structure. From the risk computed and depending on the strength of the structure, decision can to taken where the structure has to be Strengthened or Retrofitted for the future Earthquake and to preserve the Rich Cultural Heritage.
