4 These sizes assume a dry condition of use and a increase for duration of load (as for snow loading) as applicable to wood members. Sizes shown should also be checked for shear, deflection and other applicable strength properties and design considerations. For determining glulam roof beam sections an Fb value of 2400 psi, modified by the AITC volume effect factor, was used. Floor beam sections are compared on the basis of equivalent stiffness (E1) only assuming a dry condition of use for the wood members. Sizes shown should also be checked for shear, bending and other applicable strength properties and design considerations. For determining glulam floor beam sections, an MOE value of 1,800,000 psi was used.

5 Solid sawn sections are based on the assumption of using either a select structural or No. 1 visual grade having the following assumed design values: Members 2 to 4 inches thick and 5 inches and wider: Members having a least dimension of 5 inches or greater: Steel sections were selected as the most economical from the "Manual of Steel Construction," AISC, 8th Edition.
