beams used as simple span roof members in snow load areas (DOL factor = 1.15) and for non-snow loads (DOL factor = 1.25). Tables 4 and 10 provide similar information for floor members. The tables can be used to size such members for preliminary design. Final design should include a complete analysis, including bearing stresses and lateral stability. See Design Examples 2 and 3 for examples of preliminary design using glulam beam load-span tables. Allowable loads For
