How much OSB can be stacked onto a floor deck without damaging the trusses?
During the construction process, it is common practice for builders to store stacks of building materials on top of floor truss assemblies. Unfortunately, a check to see if this “construction loading” causes excessive stresses in truss members is far less common. Trusses that are overstressed due to construction loading may exhibit loosened connector plates, hairline compression fractures, and excessive sagging. These, in turn, may lead to problems ranging from finishing difficulties to structural collapse.
