Analysis and design are in accordance with the [CC 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. Glulam design values are for materials conforming to ANSI 117-2015 and manufactured in accordance with ANSI <br /> A190.1-2012 <br /> 4. GLULAM:bxd=actual breadth x actual depth. <br /> 5. Glulam Beams shall be laterally supported according to the provisions of NDS Clause 3.3.3. <br /> 6. GLULAM:bearing length based on smaller of Fcp(tension), Fcp(comp`n). <br />
