Thanks everyone for your very interesting answers, they are very much appreciated.
Prex sounds like he wants an apology from me - for posting the question on this forum. I do not know why he bothers to reply, when he writes patronizing comments such as:

Hmmm...So it seems that torsional constant is something that can not calculated for an arbitrary section very easily.
Does it involve masses of formula and a huge bunch of number crunching?
Also
Yakpol - what does "mesh the section by finite element first"
mean?
Okay I understand that-
The polar moment of inertia cannot be used to analyze shapes with non-circular cross-sections. In such cases, the torsion constant can be substituted instead.
So how can I determine torsion constant of various cross sections without having to use a different formula for a...
Hi I have written a program in visual lisp (part of Autocad)
that determines the cross sectional properties of a composite concrete beam section. Composite materials are either beam concrete, topping concrete, strands and rebar. It gives the moment of inertia, centroid and section modulus, using...
