Floor joist span tables are tabulated based on allowable deflection limits of L/360. Floor live loads range from 30 psf for sleeping areas to 40 psf for other occupancies. Ceiling joist span tables are tabulated based on allowable deflection limits of L/240. Typically a user will know the span and desired spacing for a given…
No. An engineer or architect should design cantilever members. Design of cantilever beams involves many variables including load, cantilever span and interior or back span. Often the load is not a single uniform distribution over the length of the member, and other additional loads are present, such as point loads at the end of the…

The Treated Wood Council has developed a fact sheet on CCA-preserved wood.
The requirement for panels or let-in bracing in the corners of conventionally-constructed walls is, in general a non-engineered detail that provides lateral resistance of the wall assembly and structure when subjected to lateral loads such as occur during wind or seismic events. Overturning restraint, in this case is provided by the dead load acting on…

Yes. From section 9.1.3 of the NDS: The term “wood structural panel” refers to a wood-based panel product bonded with a waterproof adhesive. Included under this designation are plywood, OSB, and composite panels. The term “composite panel” refers to a wood structural panel comprised of wood veneer and reconstituted wood-based material and bonded with waterproof…
