An outdoor wood deck system for a restaurant is to be built using No. 2 Douglas Fir- Larch dimension lumber floor joists spaced at 16 in. o.c. The flooring will be 2 in. nominal wood decking with a weight of 4.2 psf and the design occupancy live load is 100 psf. It is likely that the moisture content will exceed 19% during service and non-incised treated lumber will be used. The span of the floor joists is 14 ft. Determine what size floor joists are adequate for moment and shear using either ASD or LRFD (your choice). Begin with an assumption of C= 1.1.
