Abstract:
Damage and loss assessment of reinforced concrete elements are based in part on the length, width, and areal density of cracks. Crack information is traditionally collected using a crack width card and transferred to drawing sheets, which is both approximate and labor-intensive. An automated procedure involving digital image processing was developed and deployed to collect and process crack data. The procedure was developed and validated using data from the cyclic testing of nine reinforced concrete shear walls of varying aspect and reinforcement ratios.
