Retrofitting and Reinforcement Design of Steel Platforms Made of Beam and Brace

Abstract:

Combined with the actual project that Rehabilitation and Strengthening of cleaning workshop at Longfeng refinery, three structural schemes of platforms are provided in this paper, and finally steel girder-diagonal brace scheme is selected through comparative analysis. Load, material and selection of section size for platform structural members are given. Deformation and internal force of structure are obtained by theory and PKPM analysis, the reasonableness that the member section is selected is verified. Connection design and specific structural measures are given, and finally the reinforcement design and checking for the carbon fiber of the original frame column is carried out, and these can provide reference for similar Retrofitting Project.
