Strongbacks are horizontal members that attach perpendicularly to a series of open web joists, inside the floor cavity. Their purpose is to reduce vibration while increasing floor comfort and performance. During construction, they also prevent joist rollover.
What is a construction Strongback?
A strongback is a beam or girder which acts as a secondary support member to existing structure. A strongback in a staircase is usually ordinary two-by dimensional lumber attached to the staircase stringers to stiffen the assembly.

Are hanging beams load bearing?

Should floor trusses be braced?
With floor trusses, bracing becomes a permanent part of the floor structure. Bracing prevents trusses from bending, twisting, or otherwise deforming. The ends of bottom-chord-bearing trusses are designed to be tied together with 2×4 ledgers that also serve as a nailing base for the perimeter of the plywood deck.
How do Rafter ties work?
Rafter ties are installed between opposing rafters, and they should be installed as close as possible to the top plate. Rafter ties resist the outward thrust that rafters exert on the exterior walls. They help keep walls from spreading due to the weight of the roof. When the walls spread, the ridge board might sag.
