Analysis vs. Allowable Stress and Deflection using NDS 2012 :
Criterion Analysis Value Design Value Unit Analysis/DesignShear fv = 63 Fv' = 155 psi fv/Fv' = 0.41
Bending(+) fb = 1128 Fb' = 1157 psi fb/Fb' = 0.98Dead Defl'n 0.12 = <L/999
Live Defl'n 0.34 = L/518 0.48 = L/360 in 0.69
Total Defl'n 0.45 = L/385 0.72 = L/240 in 0.62
Design Notes:
1. WoodWorks analysis and design are in accordance with the ICC International Building Code (IBC 2012), the National Design Specification (NDS
2012), and NDS Design Supplement.
2. Please verify that the default deflection limits are appropriate for your application.
3. Sawn lumber bending members shall be laterally supported according to the provisions of NDS Clause 4.4.1.
4. BUILT-UP BEAMS: it is assumed that each ply is a single continuous member (that is, no butt joints are present) fastened together securely at
intervals not exceeding 4 times the depth and that
each ply is equally top-loaded. Where beams are side-loaded, special fastening details may be required.
