The Reduced Beam Section (RBS) is used as an effective method to improve deformation capacity on steel moment frames. However, study on flexural rigidity on composite beams with RBS has not been performed. This study proposes a useful method to calculate the equivalent flexural rigidity of composite beams with RBS on lower flange. The formulas were derived based on the energy method. FEM analysis was used to verify the theory. In addition, an eigenvalue analysis on a building model using the equivalent elastic beams with RBS was performed as an example.
