1) Construction terminology 
In construction, cross bracing is a system utilized to reinforce building structures in which diagonal supports intersect. Cross bracing can increase a building’s capability to withstand seismic activity from an earthquake. Cross bracing is usually seen with two diagonal supports placed in an X shaped manner; these supports compression and tensi...
Reinforcements in an X-shape that provides enhanced durability to a structure.
A structural technique that is used to give a structure greater durability and endurance using X-shaped reinforcements. 
Boards nailed diagonally across studs or other boards to make framework rigid.
Cross bracing is a structural component used to improve the endurance of a structure. The X-shaped reinforcement can prevent a building from collapsing completely in case of earthquakes, or a wooden chair from falling apart.
Wires, cables or girders used in certain forms of construction to keep the structure of wings or fuselage rigid.
