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 />
