Compared with concrete structure,steel frame structure has the advantages of light weight,high strength,good seismic performance,short construction period,energy saving and environmental protection.The fabricated steel frame structure is used in the design of a government revolving house in Tibet.The application of steel frame structure in high-rise residential buildings is discussed.Firstly,according to the architectural layout and preliminary structural calculation,the layout and section size of steel frame column,beam and plate are determined.Secondly,PKPM is used to calculate each performance index of the structure.Finally,the nodes and stairs and fire protection design are carried out.The results show that all the indexes of the structural model meet the requirements of the current specifications,and the design scheme is feasible and can be used as reference for related projects.
