Abstract:

The study aims to investigate the mechanical characteristics of steel fiber reinforced concrete crack for structure health monitoring. Due to the nature of harsh working environment, the steel fiber reinforced concrete is prone to crack. A tiny crack on a steel fiber reinforced concrete beam may result in severe damages. Hence, it is crucial to investigate the mechanical characteristics of steel fiber reinforced concrete crack to detect early crack semiotics. In this study, the mechanical properties of steel fiber reinforced concrete crack have been inspected by experiment tests on four specimens. The influence of the loading position has been considered in the tests. The relationship between the fracture damaged zone deformation and load have been revealed. The experiment results demonstrate that the crack opening displacement is proportional to the load in its early developing stage and there is a critical value for the crack opening displacement under fixed load. Hence, the mechanical characteristics of steel fiber reinforced concrete crack can be used to detect the crack development in practice.
