Cracking is a major source of damage in concrete structures. Inspection for cracks in concrete structures is crucial for determining the presence of damage and conducting a condition assessment. The condition assessment of civil infrastructure damaged with insufficient structural information has been a challenge. In this study, quantification of crack in concrete beam is carried out by inducing crack in the concrete beam. This work adopts an analytical method to predict crack locations on reinforced concrete beams using strain changes. The RC beam models are created by incorporating different types of cracks in different locations and evaluate the strain values using numerical method and experimental results. These strain values obtained will be utilized for the optimization of the crack in beams by analytical method. Strain values of crack induced beams are obtained by numerical validation by ANSYS. To estimate the crack location, the analytical method adopted is MATLAB. For real time application, the strain values can be continually monitored for important structures using external sensors or self-sensing concrete and the change in strain value can be recorded. The change in strain is due to crack initiation. The early detection of crack will help to do the repair and maintenance at early stage itself which will indirectly help to attain the sustainable development goals of—Innovation and infrastructure and of sustainable cities and communities.
