Research on Reinforced Concrete Beam Enlarged Cross Section Method Experiment and Finite Element Simulation

Abstract:

Increasing the beam cross section is a kind of traditional and universal strengthening methods of civil structure. The mechanical performance test were studied on the mechanics performance and deformation of four reinforced concrete beams in this study. The results show that increase of the cross section and tensile area at the bottom of the steel could effectively improve the performance of mechanical. The beam crack load, yield load, ultimate load and bending strength are increasing with cross section and mechanical. By simulating the relationship bwteen load and deflection. It is concluded that The finite element simulation of reinforced concrete beam with the reasonable concrete unit and reinforced unit can meet the demand of practical engineering.
