Question

The first requirement is that a template operate correctly (i.e,, calculate correct values). Another major consideration is that the input and output be structured in an orderly manner. A sufficient number of intermediate answers should be displayed and labeled so that the solution can be verified by hand. 6.1 Given: The roof beam in Fig. 6.A with the following information: Load: -400 lb Pg = 1600 lb D +L, (ASD) 1.2D 1.6L, (LRFD) Load combination: Span: Member size: Stress grade and species: Unbraced length: Moisture content: Live load deflection limit. L=8ft 4 X 8 No. 1 DF-L MC s 19 percent Allow. ? L/360 Find: a. Size category (Dimension lumber, B&S, or P&T) b. Reference design values: F, F, and E c. Adjusted ASD values: F, F and E d. Actual stresses (ASD) and deflection: fb fe, and ? e. Compare the actual stresses and adjusted design values, and determine if the member is adequate (ASD). f. Nominal LRFD values: Fon F, and E g. Adjusted LRFD values: Fon F and E h. Adjusted LRFD moment and shear resistances: M, and v i. Factored moment and shear (LEED), and actual deflection: M, V,, and ? j. Determine if the member is adequate (LRFD). bnUL FL ? ? Figure 6.A
