I'am actually a Entry Level BLDG Inspector and I've been presented w/ a Contractor who has completely gusseted some flat roof trusses which have been damaged in a fire resulting in a negative camber of at least 4", he has jacked up the trusses and applied 7/16' OSB across the entire span of the flat truss, My concern is: has the excessive rigidity imposed on the required deflection enough that the load transfer has gone from Vertical to a Lateral Shear imposing on the exterior walls?
