1前言建筑物消防性能化设计的核心问题是人员逃生的可用时间大于所需时间,尽管这一要求在许多规范中的表述方式有所不同,但本质都是一样的,因而在性能化设计和使用计算机软件过程中,估计安全疏散所需时间是非常重要的一个步骤。同时在计算机模拟过程中,假设每一个人都能接收到火灾信号,并在一定的延迟期后开始向出口疏散,而这个延迟期称为疏散准备时间,这段时间从发出火灾信号开始,至建筑内 1 Foreword The core problem of performance-based fire-fighting design of buildings is that the escape time of personnel is longer than the required time. Although this requirement is expressed in many norms, the essence is the same. Therefore, Using computer software, estimating the time it takes to evacuate is a very important step. At the same time in the computer simulation process, assuming that everyone can receive a fire signal, and after a certain delay began to exit the evacuation, and this delay known as the evacuation preparation time, this period from the start of a fire signal to Inside the building
