This study focuses on the "Fire-protection Refuge Facilities" in the field of building fire prevention and safety, via foreign and domestic related research studies in assessment method and current laws and statutes,As well as according to the current domestic status to develop a proper tools of assessment as the foundation of discussion on "Fire-protection Refuge Facilities" performance.

本研究从建筑防火安全的领域「防火避难设施」方面进行研究，藉由国内外文献相关评估方法的研究以及现行法规规定，并依据国内现况发展一套适合之之改造需求评估工具，作为防火避难设施性能检讨的基础。

As it is mentioned that the public buildings have complicated structures and occupy a large space in both level surface and height, their fire safety design in the respect of fire compartmentation, safety evacuation, smoke control, construction protection and active fire-protection installations cannot be made according to the national fire protection design code.

但由于此类建筑大多具有面积大、空间高、结构复杂的特点，其消防设计在防火分区、安全疏散、烟气控制、结构抗火、消防设施设置等多方面都无法执行现行国家规范的规定，对传统的&处方式&防火设计方法提出了严峻的挑战，是当前建筑防火领域急待解决的难点问题之一。

First of all, this paper analyzes the distributing situation of sectional temperature of two steel frame models within an hour utilizing the transient thermal analyse module of ANSYS;Secondly, carries on the failure analysis to two steel frame models at high temperature and obtains the fire-resistant limit and critical temperature of steel frame, utilizing the static nonlinear analyse module of ANSYS and considering the influence of geometry nonlinearity and material nonlinearity; Finally, according to the fire-protection designing requirement of structure, deduce a method to computer the thickness of fireprotection layer for steel structure and ask out the thickness of fireprotection layer of two steel frame models according to this method .

首先，利用ANSYS瞬态热分析模块，分析出两个钢框架模型在一小时内钢框架的截面温度场分布情况；其次，利用ANSYS静力非线性分析模块，综合考虑几何非线性及材料非线性影响，对钢框架模型在高温下进行失效分析，分析出两个钢框架的耐火极限及临界温度；最后，根据结构防火设计要求，推导出一种钢结构防火层保护厚度的计算方法，并据此方法求出两个钢框架模型的防火层厚度。
