What does the term ‘cross-bracing’ refer to in structural design?

The term 'cross-bracing' refers to the use of diagonal supports that enhance the stability of a structure. This design technique is employed to resist lateral loads, such as wind or seismic activity, which can cause a building or structure to sway or collapse. By forming an 'X' shape with diagonal braces between the vertical and horizontal members of a framework, cross-bracing effectively distributes forces across the structure, providing increased rigidity and strength.

The use of diagonal supports is vital in many types of construction, from modern skyscrapers to simple wooden frames, as they help maintain the integrity of the building under various stress conditions. Without such bracing, structures may be more susceptible to deformation and failure when subjected to unexpected forces.
