Radius of Gyration in Allowable Stress Design for Bridges Formulas

Radius of Gyration is used to compare how various structural shapes will behave under compression along an axis. It is used to predict buckling in a compression member or beam. And is denoted by r. Radius of Gyration is usually measured using the Millimeter for Length. Note that the value of Radius of Gyration is always positive.
