Design of wind-resistant column and bracket of light steel structure single-storey factory building
In steel structure design engineering, we often involve wind-resistant columns and supports. So today I will take you to understand the design of the wind-resistant columns and brackets of the light steel structure single-storey factory building.
Bracket Design
The cross braces and flexible tie rods in the portal frame structure can be designed according to the tie rods, while the compression rods and rigid tie rods in the non-cross braces can be designed according to the compression rods.
The internal force of the horizontal support on the rigid inclined beam of the steel structure factory building can be calculated according to the longitudinal wind load and the horizontal truss supported on the top of the column. At the same time, the force borne by the support can reduce the calculated length of the inclined beam. In addition, the stress of the strut can be ignored for the cross brace.
The tie rods in the support rods of the light steel structure single-storey factory building can be made of round steel, and the beams are connected with special connectors, and the webs of the columns are tightened with turnbuckle screws. As much as possible, the cross-section or compression rod should adopt the cross-section composed of double angle steel, and the rigid tie rod designed by the compression rod can also adopt the circular tube cross-section.
Wind Column Design
Usually, the wind-resistant column is a structural component at the gable wall of a light steel structure single-storey factory building. The wind-resistant column is not only the load-bearing frame of the gable enclosure structure, but also transmits the horizontal wind force borne by the gable to the foundation through itself and the roof system. The design of wind-resistant columns of steel structure factory building is an indispensable steel structure component in the process of steel structure design engineering, and should be highly valued.
The standard model for the design and calculation of hinged portal frame structure wind-resistant columns is generally that the column foot is hinged, and the column top is set with horizontal constraints through the support system. The wind-resistant columns of steel structure factory building is usually designed as flexural members, and the gable purlins provide plane support to improve the stability of the flexural members. In places where the mid-span bending moment of the wind-resistant column is large, it is necessary to set up the corner braces of the wall beams to ensure the stability of the inner flange under compression.
