Abstract: In this paper, shear-modified expressions for fixed end moments and reactions were obtained for various beam loading conditions using the shear modified stiffness coefficients of elastic beams derived by the authors. By taking the effect of shear on the behavior of beam elements into consideration, a set of modified homogeneous solution of the beam elastic curve equation was obtained and used to derive expressions for fixed end moments and shears for beams with various end conditions and loading. The shear-modified fixed end moment expressions were used to analyze redundant frames. The results of the analysis were then compared with those obtained using the traditional expressions for fixed end moments and shears
Keywords: Elastic curve, shear- modified stiffness coefficients, fixed end moments, redundant frames, stress distribution.
