Abstract:

Fatigue tests were conducted on two full-scale concrete box girders with premature concrete deterioration due to a combination of delayed ettringite formation and alkali-silica reaction. The specimens were loaded so that their response would be dominated by shear. Test results were used to establish an experimental S-N curve. Based on the results of these tests, premature concrete deterioration, while reducing shear capacity, does not reduce fatigue life below that assumed by the AASHTO LRFD Design Specification. Similar elements with premature concrete deterioration should be monitored visually and by NDE techniques. Visual observations should include crack widths and damage indices (extent of cracking over characteristic surface areas). NDE techniques should include acoustic emission.
