Hi Sadjad,

You can use the following two resources:

1. I think the following link may help you to know the warping constant.

2. You can also find some guidelines on the AISC torsion guide (Torsional analysis of structural steel members).

Why there is no warping constant formula for angle section in blue book

Dear Nitin, The reason is that, for an angle section Warping constant is Zero.

Not an answer but a question. What is the physical meaning of warping constant?
