An approach is presented for evaluating the vulnerability of electric cabinet in nuclear power plants. The method is based on the lognormal approach, including the maximum likelihood estimation and linear regression to establish the fragility curves. These procedures are applied for a cabinet considering various boundary conditions, which are expressed by restrained and anchored models at the base. The cabinet models have been built and verified by using the system identification technique. The results show that the fragility curves obtained for the anchored model are found to be closer to each other, compared to the fragility curves for the restrained model.
