Cracks in drywall ceiling which are attached to trusses
Cracks in drywall ceiling which are attached to trusses
(OP)
I have inspected several houses that have been damaged by falling trees and by wind loading from tornado force winds (90+ mph). On the houses that have a wood trussed roof, I have found hairline cracking in the drywall ceiling joints at the interior of the ceiling. These cracks do not occur around the perimeter as with "truss uplift". I have attributed these cracks in the ceiling to the excessive loading and the natural downward deflection of the bottom chord. Any thoughts?

Are the trusses longer span or scissored (less stiff) which would deflect more with your dynamic loads?

Check the top and bottom cords for cracking, and if the truss sheets are available the correct bracing and connectors.
