Capacity Analysis of Large Diameter Drilled Shafts with Defects
When a drilled shaft is rejected because of anomalies detected by non-destructive evaluation (NDE), arguments arise because NDE interpretation is often quite subjective. Advances in NDE technology have reduced the defect detection threshold, but no procedure is currently available that can accurately and objectively show the effect of an anomaly on the ability of a drilled shaft to carry its design loads. The proposed research will develop a validated computational tool to permit direct assessment of the lateral load carrying capacity of constructed drilled shafts. This computational tool can be applied in the field to rapidly assess drilled shaft performance that will allow construction to proceed with only a minimal impact on cost and schedule by providing an objective basis for design decisions and conflict resolution.
