What Is Rimmed Steel?

A structure consisting of steel beams and columns capable of withstanding vertical and horizontal loads. For large-span or high-rise or heavy-duty industrial and civil buildings.

A structure consisting of steel beams and columns capable of withstanding vertical and horizontal loads. For large-span or high-rise or heavy-duty industrial and civil buildings.

The steel frames of civil high-rise buildings and large-span halls can be either solid-web or frame-type. Foreign high-rise buildings use more steel frames, longer construction periods, and larger component sections and weights. Such as the New York Empire State Building and Chicago Sears Building.

For industrial buildings with large spans and heavy-duty overhead cranes, the steel columns of the rigid frame are single-stage and double-stage columns to support the crane beam. The columns above the crane track are mostly solid-belt sections, and the lower sections are lattice-shaped sections. The lattice lower column can also be a reinforced concrete lattice column. Beams are generally rigidly connected with steel upper step columns by steel trusses.

The steel frame is generally arranged in the transverse direction of the building to support the dead load, snow load, use load, horizontal wind load and earthquake action of the roof or floor. Tie beams, longitudinal support crane beams, or wall panels are connected to the frame columns in the longitudinal direction to withstand vertical horizontal wind and seismic loads and ensure the longitudinal stability of the columns. The connection of steel members is generally welded, and high-strength bolts or rivets can also be used.

In addition to the strength and stability of the material, the frame members need to ensure the overall rigidity of the frame to meet the design requirements.
