Results show that when the fire zone area is large, to symmetrically distribute the evacuation staircase width of the fire zones is more effective for evacuation.

计算结果表明，当防火分区面积比较大时，疏散楼梯在防火分区四周均匀分布有利于人员疏散；共用楼梯的设置，既有利于人员疏散，又可以提高楼梯的利用率；适当减小防火分区的面积可以缩短人员疏散的距离，使得疏散时间减少。

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。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
