Lateral bracing is the term we use to refer to any pieces on a bridge that help keep the sides (trusses) from twisting. It also helps keep the top chords of the bridge from bending or deforming in or out.
Q. How do you brace roof trusses?
Temporarily brace the first truss back to the ground, plumb, straight and in the correct position. Brace each successive truss back to the first truss with TrussSpacers. Alternatively, use a gauging rod to accurately space them and install continuous temporary ties to secure the trusses.

Q. How do you stabilize trusses?
Install a length of 1-by-4-inch framing lumber across the top cords, or rafter sections, of the trusses as a brace. Drive an 8-penny nail through the brace and into each cord. Move the ladder as you go. The trusses are now stabilized and ready for roof sheathing.
Q. What is cross bracing for trusses?
In construction, cross bracing is a system utilized to reinforce building structures in which diagonal supports intersect. Cross bracing is usually seen with two diagonal supports placed in an X-shaped manner.
Q. What is the maximum allowable deflection when handling wood trusses?
Codes provide the maximum allowable deflection limits for floor and roof trusses, which is based solely on the truss span. Generally, for roof trusses, the deflection in inches due to live load cannot exceed the span in inches divided by 240 (L/240) and due to total load L/180.
Q. What angle is best for bracing?
between 30° and 60°
Bracing is most efficient when placed at angles between 30° and 60°. With steeper bevels, the end connections can be cumbersome. Any brace configuration can be used to make up a horizontal bracing system, as long as a complete load path is available to transfer the load into the lateral load resisting system.
Q. Which is the best way to brace a truss?
Temporary and permanent bracing includes diagonal bracing, cross bracing and lateral bracing. It is important to temporarily brace the first truss at the end of the building. One method calls for the top chord to be braced by ground braces that are secured by stakes driven in the ground, preferable outside and inside.
Q. How big should the spacing be on a truss?
The bottom chord is to be securely anchored to the end wall. Additional trusses are now set and connected together with continuous rows of lateral bracing on the top chord. These are typically spaced at 4′,6′,8′ or 10 feet on centers along the lenght of the truss. Refer to BCSI 1-03 for diagonal spacing.
Q. Who is the leading supplier of roof trusses?
MiTek Industries, Inc. is the leading supplier of connector plates, truss
Q. Do you need splicing for a truss roof?
Proper bracing and the splicing of that bracing into long runs is essential for trussed roof systems and should always be given proper attention. In many situations it is a good idea to seek the advice of a structural engineer to help with the design of the overall truss bracing system.
