Steel Roof Cross Bracing

To counteract this pressure steel buildings utilize different forms of bracing in the roof and walls to transfer the loads.

Steel roof cross bracing.

In braced construction beams and columns are designed under vertical load only assuming the bracing system carries all lateral loads. Roof bracing is the secondary structure of the steel building which include lateral horizontal bracing and longitudinal horizontal bracing. Also called x bracing is a tension only bracing system. 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.

A steelbrace is made from metal strapping and has a slight bend along the centre line. Metal buildings face constant stress from wind forces including torsion shear compression and lift. It is used in other parts of the roof as well for example the bottom chords and webs. It may be located in the roof and walls of a building between frame members transferring longitudinal forces to the foundation.

Braced frames are a very common form of construction being economic to construct and simple to analyse. Bracing which provides stability and resists lateral loads may be from diagonal steel members or from a concrete core. Economy comes from the inexpensive nominally pinned connections between beams and columns. For most steel buildings x bracing each wall with cables provides all the bracing that is needed.

However high wind loads high snow loads high seismic activity or a large number of framed openings might result in alternative bracing methods.
