钢结构建筑的消防安全性能化设计——系统方法探析

根据钢结构建筑构件耐火性能的特点，应用建筑防火安全性能化设计系统方法对钢结构建筑发生火灾时热、烟对建筑结构和建筑内人员的影响进行了分析研究，确定了火灾下人员与建筑结构的安全准则。运用FDS4．0对一建筑实例建模，通过模型与建筑实际火灾相似性的计算机数值模拟研究，得出了火灾情况下建筑内的热、烟蔓延情况，同时采用ANSYS8．0分析技术对火灾下钢结构的结构反应进行了研究。以性能化设计系统方法对钢结构建筑发生火灾进行了耐火分析研究，在此基础上给出了定量的分析方法，为钢结构建筑的火灾安全工程设计和应用提供了一种新的技术。

Fire safety performance-based design of steel-structural building: exploration of systematic technology

Based on the fire resistance performance of the steel structure, this paper analyzes the practical problem arising from the steel structure design, applies the performance-based design concept to studying the movement of hot smoke in steel structure building in fire, modeling fire by software FDS4. 0, and studying the comparability between the modelled fire and actual fire in building. The peper also analyzes the performance of the steel structure in fire by software ANSYS8. 0, studies the fire resistant capability of steel-structural building by the system technique of performanced-based design and provides new technique for the fire safety design and application of the steelsturctural building.
