Preliminary Design of New Escape Chute System for Multi-Storey and High-Rise Buildings and Simulation Analysis of Personnel Escape

With the rapid development of high-rise buildings in China, fire safety and evacuation have been widely concerned by the society. Based on many years’ research on the existing evacuation forms of multi-storey and high-rise buildings, the author puts forward a New Escape Chute System (hereinafter referred to as NECS) consisting of “Double Spiral Chutes and Double Vertical High-elasticity Chutes”. And the author takes a high-rise office building as an example for preliminary design, and uses special software to simulate the whole process of evacuation and escape, so as to compare and analyze the differences in escape time caused by the different evacuation methods. The research shows that the evacuation time of people can be effectively shortened by using NECS, which fully verifies the effectiveness of the system.
