Research on the Fire of High-rise Residential Building Based on Pyrosim Numerical Simulation

Abstract

The pyrosim software is used to simulate the smoke characteristics of unit high-rise residential buildings, and the change rules of fire smoke characteristics such as smoke spread rate, visibility, harmful gas concentration, and fire temperature were obtained. The results show that when the fire occurs for 60 s, the environment of the fire site is suitable for evacuation, and the door state of the fire room has a great influence on evacuation. The results of numerical simulation can provide a theoretical reference for fire protection design and evacuation plan of unit high-rise residential buildings.
