Support systems are structures used to provide stability and strength to a building or structure. The term support system can refer to four different components: LEGS, RIGGING, bra, and shoring. LEGS are the vertical supports that hold up a structure, while RIGGING is the horizontal support that helps keep the structure in place. A bra is a type of support system that is used to provide additional stability to a structure, while shoring is a type of support system that is used to prevent a structure from collapsing. Finally, bras are a type of support system that are used to provide additional support to a structure.
