Grid structure: a spatial structure composed of multiple components connected by nodes in a certain grid form. It has the advantages of space stress, light weight, high stiffness and good seismic performance. Grid structure is widely used as the roof structure of gymnasiums, exhibition halls, clubs, theaters, canteens, conference rooms, waiting rooms, hangars, workshops and so on.

Frame structure: it is composed of beams and columns, and the cross section of the members is small, so the bearing capacity and stiffness of the frame structure are low. Its mechanical properties are similar to those of vertical cantilever shear beams. The higher the floor, the slower the horizontal displacement, and the high-rise frame bears great horizontal force in both vertical and horizontal directions.

Wood structure, brick-wood structure, brick-concrete structure, reinforced concrete frame structure, reinforced concrete frame shear wall structure, reinforced concrete frame tube structure, steel structure.

Steel types: hot rolled, cold drawn, cold drawn, round steel and ribbed steel.

Heavy steel structure: it is mostly used in petrochemical plant facilities, power plants, long-span gymnasiums, exhibition centers, high-rise or super-high-rise steel structures.

Light steel structure: a small structure, mainly used when steel is scarce and reinforced concrete structure is not suitable. It is not widely used now, so it has been basically removed in the revision of steel structure design code.
