某高层建筑交易大厅性能化消防设计

Performance-based fire design of trading hall in a high-rise building

基于某高层建筑交易大厅结构设计不符合消防规范的情况,结合结构特点及建筑内人员和消防设施的设置,提出性能化消防设计的思路。设定火灾场景,利用FDS模拟烟气运动,利用Pathfinder模拟人员疏散。结果表明,建筑消防设计能够满足火灾人员安全疏散的要求,为类似建筑消防设计提供参考。

As structure design of trading hall in a high-rise build- ing doesn＇t meet the fire codes, combined with feathers of the building and setting of fire control facilities, performance-based fire design was proposed. Set fire scenarios, used FDS to simu- late smoke spread, and Pathfinder for people evacuation simulate. The results showed that fire design of the building can en- sure safe evacuation in case of fire, giving reference for fire de- sign of similar buildings.
