Effective Torsional Constant for Restrained Open Section
Publication: Journal of Structural Engineering
Volume 124, Issue 11
Abstract
A simple, easy-to-apply effective torsional constant for the rotational stiffness of a restrained open section was developed. This effective torsional constant takes both the pure torsion and the warping torsion into acccount. The final result is a simple formula for a modified torsional constant, which is in terms of unbraced length and can be easily calculated. The constant then can be used for any generic finite-element structural analysis program.
