Abstract
When an earthquake occurs, indoor objects oscillate and fall, creating a hazardous evacuation environment. However, physical effects of oscillating and falling indoor objects during earthquakes are often ignored in the existing crowd emergency evacuation simulation studies. As a result, existing models will produce predictions that differ from the outcomes of real events. Here we propose a physics-based simulation model for an indoor seismic event scenario, focusing on movable and flexible components. We predict the motion of movable components during earthquakes using simulations based on seismic data and physical laws. In doing this, we also simulate oscillations of flexible components using a driven harmonic oscillator model. The results showed that the simulated scenario had a high degee of physical realism and rationality.
