摘　　要：某大型商贸城分A、B、C区,采用带移动天窗的"分隔内庭"设计。设A区发生火灾,按自动喷水灭火系统失效与否设置两种情况,经计算对B区物品的最大热辐分别为2.1kW/m2和8.3kW/m2,均不会导致火灾蔓延到B区。经FDS模拟,采用"分隔内庭"设计情况下烟气到达危险状态时间比采用传统设计情况下长。采用"分隔内庭"设计对设计人员要求高,并需专家会论证。The design of separation atrium with movable skylight was used on a large emporium which have 3 compartments of A,B and C.Two scenes of the sprinkler does work or does not work under fire were set in compartment A.The biggest Heat Release Rate in two scenes form compartment A to goods in compartment B were 2.1 kW/m^2 and 8.3 kW/m^2.The time before the danger with the design of separation atrium was longer than which with the design of tradition design according the simulation of FDS.The use of separation atrium needs more to designer and needs the demonstration of experts.
