The steel frame structure is mainly composed of steel beams and steel columns. The steel beams and steel columns are constructed into a stable space frame system by welding or bolting.
Steel truss structure: The steel truss structure is composed of rods connected to each other. These rods are hinged or rigidly connected to form triangular units. Many triangular units are combined together to form a large-span space structure.
二.Grid and grid shell structure
Grid structure: The grid structure is a flat space structure composed of steel pipes or steel rods in a specific grid form. Its uniqueness lies in the ability to bear force uniformly in both directions, which has obvious advantages in the application of large-span roofs. Grid shell structure: The grid shell structure is a curved grid structure. It has good rigidity and unique aesthetics. It is often used in dome buildings. Gate frame structure: The portal frame structure is a single-span or multi-span frame system formed by rigidly connecting steel columns and steel beams with variable cross-sections.
三.Cable suspension and tension structure
Cable suspension structure: The cable suspension structure mainly uses high-strength steel cables to bear tension, and forms a large-span coverage space by rationally arranging the steel cables and supporting structures. Tensile structure: The tensile structure is based on the cable suspension structure, and further optimizes the structural force performance through tensioning rods and other methods. Combined structure: The combined structure organically combines steel and concrete to give full play to their respective advantages.
