NDS® 2018 Standards Tutorial 1: Combined Bending and Axial Compression Example (ASD)
The example is taken from the 2015 NDS Examples – Beams, Columns, and Beam-Columns (DES220). Page 53.
A No. 2 Southern Pine 2×4 oriented flatwise is being considered for use as a member within the top chord of a parallel chord gable end truss. The member is 3 ft long (between panel points) and will be subjected to axial compression forces of 300 lb (DL) and 600 lb (SL), concentrated loads of 50 lb (DL) and 100 lb (SL) at the midpoint of the member on its wide face and 120 lb (WL) of the midpoint of the member on its narrow face. Lateral support is provided only at the ends of the member and the ends are considered pinned.
Check the adequacy of the beam-column for bending and compression for the appropriate load cases.
