چکیده
|
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 eulerbernulli beam is proposed to represent longterm 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 wellknown 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.
