Analysis and design are in accordance with the ICC International Building Code (IBC 2018) and the National Design <br /> Specification (NDS 2018), using Allowable Stress Design (ASD). Design values are from the NDS Supplement, <br /> 2. Please verify that the default deflection limits are appropriate for your application. <br /> 3. Sawn lumber bending members shall be laterally supported according to the provisions of NDS Clause 4.4.1. <br /> 4. BUILT-UP BEAMS: it is assumed that each ply is a single continuous member(that is, no butt joints are present) and <br /> that each ply is equally top-loaded.Where beams are side-loaded, special fastening details may be required. <br /> 5. FIRE RATING:Joists,wall studs, and multi-ply members are not rated for fire endurance. <br />
