Components of steel structure canopy

Steel structure awnings are mainly used to block wind and rain between buildings and can be seen everywhere in life. Next, HBKconstruction will explain to you what the components of the steel structure canopy are.

1. Steel structure awning board

Different from the cantilever plate structure, the steel structure awning plate is a plate supported on four sides, so it should be determined according to the ratio of the length of the long side and the short side of the plate whether it is calculated as a one-way plate or a two-way plate. The plate thickness confirmation and reinforcement calculation are the same as those for plates supported on four sides.

2. Steel structure awning side beams

The side beams of the steel structure canopy are supported on cantilever beams. If the steel structure canopy board is a two-way board, the load borne by the beam is mainly the partial load transmitted from the board and its own weight. If the side beam is on the one-way steel canopy board On its short side, the only load it bears is its own weight. Internal forces and reinforcement calculations can be performed approximately based on simply supported beams or continuous beams, while meeting structural requirements.

3. Steel structure canopy beams

The cantilever plate of the steel structure canopy is supported on the steel structure canopy beam. The load borne by the cantilever beam is mainly the partial load transferred from the plate, the load transferred from the side beam and its own weight. Under these load effects, the shear force and bending moment of the cantilever beam at the beam root section are relatively large, and this section is used as the stressed section to calculate the bending and shear bearing capacity.

4. Steel structure canopy beams

The steel structure canopy beam of the cantilevered beam plate structure is similar to the cantilevered plate structure, both of which are bending, shearing and torsion members. The difference is that the torque in the cross-section is not uniformly distributed along the length of the beam, but has a concentrated moment effect. It can be equivalent to a uniform moment, or the torque can be calculated directly.
