Steel Roof Cross Bracing

A steelbrace is made from metal strapping and has a slight bend along the centre line.

Steel roof cross bracing.

Fly bracing is the secondary structure which between roof beam and purlin column and wall girt bracing connected with roof beam and purlin in 45 degree. In braced construction beams and columns are designed under vertical load only assuming the bracing system carries all lateral loads. It is used in other parts of the roof as well for example the bottom chords and webs. Roof bracing is the secondary structure of the steel building which include lateral horizontal bracing and longitudinal horizontal bracing.

Metal buildings face constant stress from wind forces including torsion shear compression and lift. To counteract this pressure steel buildings utilize different forms of bracing in the roof and walls to transfer the loads. It may be located in the roof and walls of a building between frame members transferring longitudinal forces to the foundation. However high wind loads high snow loads high seismic activity or a large number of framed openings might result in alternative bracing methods.

Roof bracing is the secondary structure of the steel building which include upper lateral horizontal bracing down lateral horizontal bracing and longitudinal horizontal bracing steel materials used q235b. Economy comes from the inexpensive nominally pinned connections between beams and columns. Bracing is often provided by a steelbrace. For most steel buildings x bracing each wall with cables provides all the bracing that is needed.

Also called x bracing is a tension only bracing system.
