基于FDS的体育馆消防设计安全性仿真模拟验证分析

Simulation and Verification of Fire Safety Design of Gymnasium Based on FDS

为了研究体育馆防火分区面积超过规范要求等问题,采用消防工程原理与方法,对某体育馆进行消防性能化设计。在满足建筑使用功能的前提下,通过实地调研考察分析,设定不同的火灾场景,运用火灾动力学软件FDS(Fire Dynamics Simulator)进行烟气运动模拟和人员疏散安全性分析,验证该体育馆建筑消防设计的安全性与可行性。研究结果表明:火灾蔓延和烟气蔓延均可以得到有效控制,人员可以安全疏散,该建筑的消防安全性是可以得到有效保证。研究结果为同类工程的消防设计提供参考。

Due to the particularity of the structural system and use function of the gymnasium,there are some problems,such as the area of the fire compartment exceeds the specification requirements.Based on the principle and method of fire engineering,the performance-based fire design of a gymnasium is carried out.On the premise of meeting the use function of the building,different fire scenarios are set through field investigation and analysis,and the smoke movement simulation and personnel evacuation safety analysis are carried out by using the fire dynamics software to verify the safety and feasibility of the building fire protection design of the gymnasium.The research results show that the fire spread and smoke spread can be effectively controlled,personnel can be evacuated safely,and the fire safety of the building can be effectively guaranteed.The research results provide a reference for the fire protection design of similar projects.
