Abstract

The design philosophy “the safety level of a performance-based designed building should not be lower than that of a prescriptive” with objectives of property protection and life safety was implemented in this paper. Three countervailing solutions were adopted to reduce fire risk in the 11664 m 2 case storage. Besides, a virtual prescriptive storage with identical length-width ratio and similar ventilation conditions as the performance-based was designed for comparison. After designing the fire development event tree and simulating six fire scenarios using FDS, the two objectives were achieved as fire severity and risk of property loss of the performance-based design storage were found to be no higher than those of the prescriptive design and ASETs were greater than RSETs for all fire scenarios.
大型仓储空间消防安全设计的比较评价方法
本文贯彻了以财产保护和生命安全为目标的“性能型设计建筑的安全水平不应低于规范要求”的设计理念。采用了三种抵消方案来降低11664m2箱子存储的火灾风险。此外,还设计了一个与性能型相同长宽比、相似通风条件的虚拟规定性储层进行比较。在设计了火灾发展事件树并使用FDS模拟了6种火灾场景后,发现基于性能的设计存储的火灾严重程度和财产损失风险不高于规定性设计,并且所有火灾场景的ASETs都大于RSETs,从而实现了两个目标。
