Evaluation of Structural Cracking in Concrete

Current procedures used for classifying the damage associated with visually observed cracking in reinforced and prestressed concrete structures generally consist of various rating criteria that are comprised of pre-established crack width limits. While such procedures can be useful for cataloguing damage progression, the procedures typically provide very little information pertaining to the structural capacity implications of concrete cracking observed in the field. The development of reinforced concrete strength assessment procedures that employ visual crack measurement data as the primary basis for capacity assessment shall better assist engineers in prioritizing rehabilitation and maintenance efforts and shall serve as valuable tools that can be used in identifying strength-related deficiencies. Center for Transportation Research (CTR) will use analytical studies to develop practical crack-based shear strength assessment procedures that are rooted in mechanical models and novel damage evaluation techniques. By way of their crack-based formulations, these procedures shall inherently incorporate influences associated with member scale, reinforcement details, and loading conditions. The procedures shall be evaluated and refined using test data pertaining to well-documented Texas Department of Transportation (TxDOT) relevant concrete infrastructure elements and subsequently shall be employed to develop crack inspection field aids that can be used by TxDOT personnel, on-site.
