Equivalent Round Section Dimension

How is the dimension for an equivalent round section calculated in the Timber Design add-on?

Answer:

The formula to determine the initial section depth di (CSA) or the equivalent square section dimension aeq (NDS) used for the slenderness ratio calculation is as follows:

di = π·d24      (CSA O86)
aeq = π·d24    (NDS)
di Initial section depth
d Diameter (section depth)
aeq Equivalent square section dimension
