Burnt buildings may have to be demolished, even if they have merely slight seismic damage, which will dramatically increase the recovery time of communities to regain their functionality. As a result, a rational fire following earthquake (FFE) simulation is important for the resilience assessment of communities after an earthquake. This work proposes a framework for the physicsbased simulation of FFE considering building seismic damage, through which the accuracy, rationality and usability of FFE simulation are improved. Specifically, the seismic damage of regional buildings is simulated using multiple degree-of-freedom (MDOF) building models and nonlinear time-history analysis. A case study of the FFE simulation of downtown Tangshan City with 230,683 buildings is performed. The results show that the influence of different ground motions and building seismic resistances on fire ignition and fire spread can be taken into account with the proposed method. The proposed FFE simulation method can serve as important technical supports for FFE prevention and disaster management.
