Which structural element is installed across floor joists to distribute loads and reduce bounce?

• A. Subflooring
• B. Sheathing
• C. Bridging
• D. Decking

Answer: (C)

Bridging is placed across floor joists to tie them together and spread loads from one joist to the next. This helps distribute vertical loads more evenly and resists twisting of the joists, reducing floor deflection or bounce. In other words, bridging stiffens the floor system by creating a small web between joists, keeping them aligned and working as a unit. Subflooring sits on top of the joists to provide a walking surface and help transfer loads to the joists, but it’s not specifically about preventing bounce. Decking refers to exterior floor surfaces, and sheathing is a panel used to reinforce walls or exterior sheathing, not the interior floor’s load distribution.
