There is a method called “generalized superpose flexural strength method” which is widely used to calculate ultimate flexural bearing capacity of Steel Reinforced Concrete Structures in Japan. This method is easier and more practical than a method calculate ultimate strength of structural members based on equilibrium of stresses and compatibility of strains. On the other hand, this method overestimates flexural bearing capacity in a certain case that concrete reaches ultimate strain yielding of steels. The author proposes a modified method which solves problem of overestimation. The modified method evaluates the yielding condition of steels properly in and case, and estimates flexural bending capacity and deformation of Steel-Concrete composite members preisely.
