Influence of the Reinforcement’s Number on the Mechanical Properties of the Reinforced Concrete Beam

Abstract:

Basing on the experimental data collected, the mechanical model of reinforced concrete beams’ gradual failure has been set up, to test differ reinforced components with loads and study the process of split. At last the influence of reinforcement’s number on components’ intensity and failure process are analyzed by using MFPA2D (Material Failure Process Analysis) software, started with the analysis of formula cracks after experiments. The results showed that the number of reinforcement is not the more the better. When ultra-reinforced beam appears, its mechanical capacity enhances but the bars won’t do their best, furthermore, it is uneconomical. Accordingly, less-reinforced beam should also be avoided for safe. Everything possible should be made to avoid ultra-reinforced beam and less-reinforced beam in engineering. By all means, this conclusion has practical significance during our practice.
