Steel Roof Wind Bracing

Metal buildings face constant stress from wind forces including torsion shear compression and lift.

Steel roof wind bracing.

If its a truss roof then wind bracing is important when they design the roof they also design a wind bracing plan so the wind braces are positioned correctly. Requires no turn buckle or tensioning device. 3 s p e e d b r a c e s i z e s for roofs with truss spans greater than the maximum spans in table 1 but less than 13 0 m adopt same bracing layout but use double bracing. Zee girt a wall structural is a horizontal structural member that is attached to the sidewall or endwall columns and supports paneling.

For most steel buildings x bracing each wall with cables provides all the bracing that is needed. Made up of rods angles and cables these components are essential within the plane of the roofing system and wall panels for load transfer. Ideal for use in all wind speeds including cyclonic areas. To provide stability during erection.

Roof battens steel thickness grade fixings tested and certified. Bracing is used between structural members of metal buildings. Plan bracing is located in the plane of the roof. Pre punched and formed galvanised steel tension bracing system designed to brace roof trusses and wall frames.

Bracing transfers seismic and wind loads from endwalls and sidewalls to the foundation. This pre punched and formed galvanised steel brace. Usually the floor system will be sufficient to act as a diaphragm without the need for additional steel bracing. Steel buildings are engineered to wind and snow loads for your area.

At roof level bracing often known as a wind girder may be required to carry the horizontal forces at the top of the columns if there is no diaphragm. For roofs with truss spans less than the maximum spans in table 1 use bracing layouts as specified in typical bracing layouts. Is applied to the truss or wall frame producing a quick and simple fixing. This bracing is used to counteract the force from the wind and seismic on each surface of the building.

To counteract this pressure steel buildings utilize different forms of bracing in the roof and walls to transfer the loads. Tie down bracing other stuff. Wind loads on walls. See figure on the right.

To transmit any frictional drag forces from wind on the roof to the vertical bracing. Bracing is a key element in creating a strong foundation to fight seismic wind and crane thrusts. Part of that engineering comes in the form of steel building bracing. To transmit wind forces from the gable posts to the vertical bracing in the walls.

The primary functions of the plan bracing are.
