GB/T 31593.9-2015

This standard provides methodologies for evaluating human behavior and movement during building evacuations, including factors like occupant density, walking speed, and decision-making under fire conditions. It is applied by fire safety engineers and building designers in China to model evacuation scenarios, assess egress system adequacy, and validate performance-based fire safety designs for commercial, residential, and public assembly buildings. The guidance supports compliance with fire safety regulations by enabling quantitative analysis of occupant safety during emergency egress.
