Calculation Model for Crack Width of Smart Film Based on Shear-Lag Theory

Abstract:

Detection of crack width is crucial in structural health monitoring of concrete bridge. In this paper, the smart film has been employed to monitor the crack initiation and development in concrete bridges. Under plane stress and two dimension conditions, through structure mechanics behavior analysis, the calculation model for crack width of smart film was constructed based on the shear-lag theory. Calculation model study demonstrated the relationship between crack width and diameter of the smart film, and the crack width could be calculated.
