I created a custom section within section wizard to simply find the torsional properties (torsional constant and warping constant) of a lower bridge chord which we are proposing to add additional weight to.
When I view the properties of the section I created, the only relevant property appearing is "Torsional moment of inertia". Is this program capable of determining the torsional constant and warping constant of the created section?
See below for printout.
Thank you
