Answer:
The reinforcing technique used in roof trusses is often called "bracing." Bracing is employed in roof truss systems to enhance their stability and strength, preventing lateral movement and ensuring that the trusses can effectively bear the loads placed on them. Bracing can take various forms, such as diagonal braces, cross braces, or other structural elements designed to provide additional support and prevent the trusses from buckling or twisting under different types of loads, including wind and snow loads. The specific type and configuration of bracing depend on the design requirements and the structural characteristics of the building.
