The experimental research of bending for the reinforced concrete simply supported beam
Through the experiments of five simply supported reinforced concrete beams in bending failure process. Analyzed the basic mechanical properties and rules,and the beam damage morphological characteristics of the concrete beam under a concentrated load. The results showed:the maximum displacement data which is calculated according to the experimental data is slightly smaller than that calculated according to the stand-ard,the longitudinal tensile stress increases linearly with the increase of the load before the yield,in the process of bending failure of beam’s cross section,the change law which the strain along the section height of the concrete before the crack happened to the concrete is basically con-sistent with the assumption of plane section.
