Abstract:

The advantages and engineering practice cases of prefabricated steel frame structure withdiagonal bracing joints are introduced, and its structural layout, component form, construction measures,connection joints and stress mechanism are analyzed. Aiming at the characteristics of the frame beam ofthe structure, the small diagonal bracing at the end of the column, and the large number of components,the corresponding structural calculation method is proposed, which solves many calculation problems ofthe prefabricated steel frame structure with diagonal bracing joints, including the selection of appropriatecalculation software, the simplification of the truss beam, the determination of the effective lengthcoefficient of the column, and the checking of the detailed strength of the truss beam. The reliability ofthe calculation method is verified by comparing the calculation results with the design specifications,experimental research and engineering practice.
