Abstract
To improve the fire separation efficiency of connected commercial complexes,this paper takes a large commercial building as an example to systematically analyze the comprehensive application effects of the NFPA 92B point source radiation model,FDS multi-physics field coupling simulation and thermal load integral criterion technology.The results show that after the construction is completed,the peak value of thermal radiation intensity of the shops on the opposite side of the atrium is 9.68 kW/m2(lower than the threshold of 12.5 kW/m2),the peak value of flue gas temperature is 910℃,the delay of smoke exhaust response is 45 seconds,and the visibility maintenance time is 120 seconds,all of which meet the requirements of the specifications.In conclusion,the optimized design scheme of the 6-meter-wide fire isolation belt precisely curbs the spread of fire and has high engineering reliability.It can be promoted and applied in large-space buildings such as large commercial complexes and transportation hubs.关键词
