Where is temporary horizontal bracing attached when erecting trusses?

Temporary horizontal bracing is attached near the ridge line of the truss during erection to provide stability and prevent lateral movement as the structure is being assembled. This location is strategic because it helps to maintain the vertical alignment of the truss and ensures that the stresses are effectively distributed throughout the structure. By securing the bracing at this high point, it allows for better control over the truss's shape and prevents buckling or twisting that can occur if the truss is not adequately stabilized.

The ridge line is the highest point of the truss, and securing the bracing there allows for greater resistance to forces that can cause instability. This reinforces the overall integrity of the structure during the construction process. Proper bracing is crucial not only for safety and structural stability but also for ensuring that the trusses can be installed correctly in their final positions.
