Fly Bracing is the secondary structure which between roof beam and purlin , column and wall girt , the bracing connected with roof beam and purlin in 45 degree , connected on the bottom flange plate of roof beam .
- The distance of flange bracing in 3m for light steel structure building reduce the calculated out-plane length of roof beam ,reduce the steel quantity enlarge the stability of steel building .
- As for heavy steel workshop , the roof purlin used H section beam , flange bracing will used double L angle steel which could reduce the quantity of roof purlin ,much more economical for the workshop building .
- Fly Bracing could reduce the out-plane calculated length ,enlarge the stability of out-plane ,When lateral support point is required for the inner flange of the roof beam and the column, the fly bracing can be arrange between roof purlin or wall girt connected to the outer flange , bracing usually used L angle steel .
- Fly bracing is used to ensure the local stability of the compressed part of the bottom flange of the roof beam .
