Calculate Column Face Dimension for Tapered Wood Column
dmax - Maximum dimension of that face of the tapered column
dmin - Minimum dimension of that face of the tapered column
d - Representative column face dimension
d(a=) - Representative column face dimension
(a=0.70) - large end fixed, small end unsupported or simply supported.
(a=0.30) - small end fixed, large end unsupported or simply supported.
(a=0.50) - both ends simply supported and tapered toward one end.
(a=0.70) - both ends simply supported and tapered toward both ends.
