Pipe truss structure is used in the 60 meters cross-connections modeling of the library and the culture museum roofs, and sliding supports are used at one end. Cast-in-situ concrete vierendeel grid is adopted in the audience hall roof of the theatre, and cast-in-situ concrete truss is used in the theatre proscenium arch. Both the steel awning of the main theatre entrance and partial folded plate stairs in the theatre basement are analyzed and calculated, so that the structure design of the theatre is optimized. The structural design of this project can be used as a reference to the design of structures that are of the same type.Keywords: pipe truss structure, cast-in-situ concrete vierendeel grid, cast-in-situ concrete truss, folded plate stairs
