For the steel frame structure, with the increase of the number of layers and height and bearing a large vertical load, the lateral resistance (wind load, earthquake action, etc.) requirements become the primary bearing characteristics of the frame.

The steel frame structure system is generally divided into frame structure, frame bracing structure, frame shear wall structure, and frame tube structure.

Frame structure: The frame is composed of columns and beams, which bear vertical and lateral forces. Steel columns generally use H-shaped steel, box-shaped steel columns, or steel tube concrete columns.

Frame bracing structure: The frame is composed of columns and beams, and bracings are provided between the columns to resist lateral forces.

Frame shear wall structure: similar to the frame bracing structure, except that the bracing is replaced with a shear wall to resist lateral forces.

The shear wall is generally a concrete slab or steel plate, or a steel-concrete composite structure with better lateral stiffness than bracing and is more flexible in layout, suitable for higher building structures.

Frame tube structure: The structure is generally composed of a reinforced concrete core tube and an outer ring steel frame.

The system form uses pure steel frames in the horizontal direction and arranges an appropriate number of vertical inter-column bracing in the longitudinal direction to strengthen the longitudinal rigidity, reduce the amount of steel used in the frame, and form a larger space.
