Based on the Timoshenko beam theory, wherein shear distortion is included in the transverse displacement of beams, a table of fixed-end moments is derived. The equations for the moments given in the table include a shear correction factor which is a function of the ratio of the beam's croos-sectional radius of gyration to its length. The fixed-end moments reduce to the values based on classical beam theory for vanishing shear correction factor. Also in cluded in the paper are stiffness factos for various loading conditions. The moment distribution procedure is applied in the usual manner. The effect of including shear distortion s hown in an example.
