Strongback In Attic

Wondering if maybe i can trust a better strongback like 2 x10 s to fight against ceiling cracking.

Strongback in attic.

Can the strongback bracing end at a truss without tying into an end wall. Strongbacks can be altered to allow hvac installations as long as three 3 consecutive joists are attached. The ceiling load may include items like drywall ducts recessed lights bathroom fans and attic insulation. Deep residential floor system with trusses in lengths up to 19 ft.

By installing strong backs or beams in the attic will create a solid d. Engineer said no beam required but because the wall has been in place so long i may get ceiling cracking without a beam. If i do an exposed beam on the room side it would be about 21 feet long. However in some cases the joists are intentionally built strong enough for the homeowner to later build out the attic.

Most houses attics are built without flooring and are not designed to carry the heavy load of finished space. In this historic home the ceiling joists were independent creating severer deflection. Strongback bridging is an excellent and inexpensive way to improve the overall rigidity of the floor system and eliminate vibration. Also sometimes known as a strong back a strongback is a type of construction that helps to enhance the strength of some type of structure by adding a secondary support at a key point in the design.

The idea is to provide additional support at points in which the failure of the main support network would lead to the collapse of the structure as a whole.
