Compute for the adjusted reference compressive stress with modifications, ( Fc* ) in MPa
P = 56.25 kN
support conditions:
pinned-pinned (k = 1.0)
P = total load from
governing load
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)
combined load, P = 15 kN (due to load combination, D
+L+ W)

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.

Use the following properties for reference design
values:
(a) Reference Compressive Design Value (Parallel to
Grain), Fc = 5.11 MPa
(b) Reference Modulus of Elasticity, E = 3640 MPa
Important: Emin İis given by Emin = Eo.05 (1.03/1.66) = E
(1-1.645COVE) (1.03/1.66)
