Use the hand solution to Probs. 6.1 and 6.3 as a guide to develop a personal computer template to solve similar problems using ASD and LRFD. a. Consider only the specific criteria given in Probs. 6.1 and 6.3. b. Expand the template to handle any Span length L Magnitude load P or
Un braced length lu Sawn lumber trial member size The template is to include a list (i.e., database) of reference design values for all size categories (Dimension lumber B&S, P&T) of No. 1 DF-L. c. Expand the database in part b to include all grades of DF-L from No. 2 through Select Structural.
Probs. 6.1 and 6.3
Repeat Prob. 6.1 except the unbraced length is
Prob. 6.1
Given: The roof beam in Fig. 6.A with the following information:
Find: a. Size category (Dimension lumber, B&S, or P&T)
e. Compare the actual stresses and adjusted design values, and determine if the member is adequate (ASD).
f. Nominal LRFD values:
g. Adjusted LRFD values:
h. Adjusted LRFD moment and shear resistances
i. Factored moment and shear (LRFD), and actual deflection: Mu Vu, and
j. Determine if the member is adequate (LRFD).
