Calculation:

Designer/Checker:

Input:

Metric Units

(Note: All input Metric units are converted to English units for the equations below and then the output English units are converted back to Metric)

AWC 2012 NDS Manual For Wood Construction 3.7-2, Tapered Column Face Dimension.

The following is for calculating the representative face dimension, d, for a tapered wood column, square or round.

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.

other support conditions not listed.

Maximum dimension of that face of the tapered column (dmax - in or cm)

Minimum dimension of that face of the tapered column (dmin - in or cm)

Output:

Representative column face dimension, d =
