钢结构抗火专家系统研究与开发

RESEARCH AND DEVELOPMENT ON THE EXPERT SYSTEM FOR FIRE RESISTANCE OF STEEL STRUCTURE

随着钢结构抗火计算分析理论的不断拓展,其设计方法正逐步由基于构件火灾试验的传统被动方法向基于结构整体分析的新颖主动方法演变。钢结构抗火设计是一件非常繁琐且极其复杂的多学科交叉工程,其涉及到的内容和范围越来越广泛。基于钢结构抗火专业知识和计算机领域新技术,结合专家系统的自身特点,探索性和尝试性地研究和开发出一套适用于钢结构抗火设计的专家系统,此专家系统程序的编制采用了界面化和智能化技术,具有良好的兼容性和开放性,与其他应用软件具有良好的接口技术,可大大地简化钢结构抗火设计过程,提高其设计效率。最后,通过一个抗火的设计案例检验和验证了专家系统的可行性和准确性。

With the development of calculation theory on fire resistance of the steel structure, its design method is evolved gradually from the traditional passive-methods based on the component fire test to the novel active-methods based on the overall structural analysis. The fire resistance design of steel structure is a very complex interdisciplinary project, which is involved in the more extensive content and scope. Based on the knowledge for the fire resistance of steel structure and new computer technology, with the characteristics of expert system, an expert system for the fire resistance of steel structure was tentatively researched and developed. This expert system has been prepared by using the interface and intdligent technology, which has good compatibility and openness, and may have excellent interface with other application softwares. The expert system can greatly simplify the fire resistance design of steel structure, and improve its design efficiency. Finally, the feasibility and accuracy of the expert system were tested and verified by a case of the fire resistance design.
