The differential equation of torsion is derived from first principles for tapered I-girders. It accounts for St. Venant, warping, and secondary stiffnesses. A number of boundary conditions are discussed. An analytical solution is obtained for linearly-tapered cantilever beams and is compared with finite difference solutions.
