以虚拟样机模拟为代表的计算机辅助工程(ComputerAidEngineering,简称CAE),给工程、科学以至人类社会带来急剧的革命性变化。结合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分析的理念对钢结构建筑发生火灾的热烟流动情况进行研究。通过一个实例运用计算机流体力学模拟技术对分析的建筑建模,对模型与建筑实际火灾相似性进行初步计算机数值模拟研究并对火灾情况下钢结构的结构反应进行分析。
Computer Aided Engineering (CAE), represented by virtual prototyping, has brought about drastic and revolutionary changes in engineering, science and human society. Combined with the characteristics of fire-resistant performance of steel structure building components, the concept of fire building safety performance analysis was used to study the hot smoke flow in steel structure buildings. Through an example, computer modeling of the building was used to simulate the analysis of the building, the preliminary computer numerical simulation of the similarity between the model and the building fire was conducted, and the structural response of the steel structure in the case of fire was analyzed.
