Figure 8 presents the developed fragility relationships for the considered typology of the RC school building in seismic zone 4 of Pakistan. WebThe small difference between the direct and fragility-based flood loss curve is due to using the lognormal fitted fragility functions in developing the fragility-based flood loss curve. These resulting flood curves were then compared with the HAZUS stage–damage function [ 23 ] to provide some level of benchmarking and showed a good match.
