摘要
主要研究大型锅炉钢结构的风荷载,采用中国GB/T 22395—2008《锅炉钢结构设计规范》和美国UBC 97以及ASCE 7规范对大型锅炉钢结构进行静力分析的方法。阐述两国规范风荷载的规定在锅炉钢结构设计上的应用,以及风荷载各规范之间的转换,并对3个规范的风荷载计算方法进行比较。通过一工程实例,将风荷载与垂直荷载按相关规范计算并进行组合,加载到钢架上,用大型结构分析程序STAAD V8i进行结构的空间结构分析,求解出结构的水平反力和位移以及主要构件的内力和应力比。
It was mainly studied the wind load of large power station boiler steel structure,the Chinese Specification for Design of Boiler Steel Structures（GB/T 22395—2008） and the United States UBC97 and ASCE7 specification were used for static analysis.It was elaborated the norms of the wind load provisions in the boiler steel structure design,and the wind load conversion between each standard;and it was also compared three regulating wind load calculation methods.Through an engineering example,the wind load and vertical load were combined in accordance with the relevant specification calculation,and added to that of the frame,using the structural analysis program STAAD V8i to do structure spatial analysis,it was obtained the horizontal force displacement,the internal force and stress ratio of the structure.
