APPLICATION OF THE CHINESE AND AMERICAN CODES IN DESIGN OF BOILER STEEL STRUCTURES FOR ELECTRIC POWER STATION

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 223952008) 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.
