Earthquake evacuation simulation of multi-story buildings during earthquakes

Abstract

Through combining a network-based pedestrian dynamics simulation model, simplified probabilistic structural damage assessment, and structural random vibration analysis, a fully random evacuation model is proposed for simulating and analyzing earthquake evacuation processes of multi-story buildings during earthquakes. The model simplifies the simulation of three-dimensional pedestrian dynamics, couples the emergency evacuation processes and damage processes of structures, and takes into account the randomness of pedestrian dynamics, structural damage, and earthquake excitation. The model can be used for the fast pre-evaluation or evaluation of the earthquake evacuation capabilities of multi-story buildings. The simulation and analysis of the earthquake evacuation process of a three-story office building, in which a total of 60 persons work in the first and second stories, illustrates the effectiveness and implementation of the proposed model.
