combination, D +L + W
total length of column member, I = 3 m
beam width, b = 6" or 150 mm (dressed)
beam depth, d = 6" or 150 mm (dressed)

Notes:
(1) The column is not braced althroughout its length.
Buckling is a concern.
(2) The column-end conditions are pinned-pinned for
buckling about x-direction.
(3) The column-end conditions are pinned-pinned for
buckling about y-direction.
(3) The moisture content is < 19%.
(4) Normal temperature conditions apply.
(5) Assume no incising was incorporated for addition
of preservatives.
(6) A fire retardant factor = 1.0 is applied.
