Torsional Constant

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I'm using Section F1 of the AISC Manual, 3rd edition, to analyze a 3/8" x 8" rectangular plate in bending about its major axis: it is subject to lateral torsional buckling.
 
J is defined as the torsional constant.  Where is the method of determining the value of J stated in the manual?  J is the polar moment of inertia of a section in "Roark's Formulas for Stress and Strain" -- is that also the definition of J used here?
