Abstract: The application of composite structure in metro depot was briefly described firstly. Then the base joint, beam-column joint, joint of upper column and lower column, joint of beam-supported column, steel chapiter reserved joint of the composite frame structure,were classified and introduced one by one. Several typical complicated situations in practical design were explained in detail, which were not covered by present codes or atlases of steel reinforced concrete (SRC) and concrete filled steel tube. Finally, based on experience, some improvements and measures to solve these problems were recommended, and their technical rationality and constructive feasibility were also expounded, which could provide some references and inspirations for the design of composite frame joints of metro depot in the future.
