超高层建筑商业裙楼性能化设计

Performance-based design of high-rise building commercial podium

总结超高层建筑商业裙楼存在的火灾危险性,如功能复杂、火灾蔓延迅速、扑救困难、人员疏散困难等。以广州东塔商业裙楼为例,分析其消防设计难点。根据消防安全工程原理和性能化防火设计思想,如准安全区、防火单元等,从裙楼防火分隔、防排烟方案、人员疏散等方面提出其消防性能化设计方案,为类似工程的消防性能化设计提供参考。

The fire hazards of high-rise building commercial podium were concluded,such as functional complexity,fire spreading fast,hard to put out,and difficult to evacuate.Taking the commercial podium of Guangzhou East Tower as an example,the fire deign problems were analyzed.According to the fire safety engineering and performance-based design,such as quasi-security zone,and fire unit,the fire safety design plan was put forward in points of fire separation,smoke control,and evacuation,which can provide reference for similar fire design.
