A simply supported wood roof beam is loaded with single point dead and roof live loads applied at midspan (PD = 400 lb, PLr = 16

00 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
