Asimply supported wood roof beam is loaded with single point dead and roof live loads applied at midspan (pd = 400 lb, plr = 1600 lb) of an 8 ft span. it is located in an industrial situation where the moisture content in-service is greater than 19%. the controlling load combinations are d + lr (asd) and 1.2d + 1.6lr (lrfd). a no. 1 df-l 4 x 8 is used for the beam and it is continuously braced (lu = 0). the allowable live load deflection is δ ≤ l/360. determine whether the beam is adequate for asd and lrfd by determining: a. size category (dimension lumber, b& s, p& t) b. reference design values: fv, and e c. adjusted asd values: f’v, and e’ d. actual stresses (asd) and deflection: fv, and δ e. compare the actual stresses and adjusted design values, and determine if the member is adequate for shear and deflection (asd) f. nominal lrfd values fvn, and e g. adjusted lrfd values f’vn, and e’ h. adjusted lrfd shear resistance: v’n i. factored shear (lrfd), and actual deflection: mu, vu, and δ j. determine if the member is adequate for shear and deflection using lrfd
