Finite Element Analysis of Influence Factors on Crack Width of Concrete

Abstract

Reinforced concrete beam structure is the composite material with high bearing capacity and high stiffness. However, the influence of load and reinforcement rate in the structure can be the cause of the cracks appearing in engineering, these will lead to the failure. Therefore, in this paper, the elastoplastic analysis of reinforced concrete beams are adopted as an example to study the influence of various influencing factors on the formation of cracks. The results show that the loading is the most sensitive to crack width, The whole variation curve of the ratio of reinforcement had a turning point. After this point, there was a slight increase in the sensitivity of the reinforcement.
