摘要

The hidden troubles for connect structure between buildings to spread the fire was analyzed, and referencing to the requirement of design of vestibule in Code, using the FDS, the fire spreading between buildings and the damage of it were researched with the example of project. The principle of ceiling design was put forward and the verification or supplementing to Code was put forward too.%分析了建筑间连结结构在火灾中引起建筑物间火灾蔓延的危险性,并对照原有规范中为避免火灾蔓延而对连廊结构设计方面的有关要求,采用计算机模拟的方法(FDS),通过对工程实例的定量研究,提出了顶棚排烟设计原则,对原有的规范设计进行了验证和补充.
