Abstract

A powerful and new theoretical approach is used to obtain an expression for the effect of creep on reinforced concrete shear deformable beams. First, a method for Euler-Bernulli beam is proposed to represent long-term behavior of concrete beams based on linear strain theory. Secondly, a formulation is developed for analyzing the strain distribution in shear deformable concrete beams. Finally, three numerical examples are included in order to compare well-known codes with the proposed method. Comparison between proposed method, FEM, codes and experimental works demonstrate that the proposed analytical procedure can effectively simulate creep behavior in reinforced concrete beams.
