Evaluation of Corrugated Metal Pipe-Arches. Volume 1

摘要

The report presents the results of an evaluation of 890 pipe-arch structures currently under jurisdiction of the Ohio Department of Transportation. Dominant modes of failure were identified through statistical analysis. The data subsequently provided the basis for selecting 50 structures for a comprehensive field visual and dimensional inspection. Upon completion of these field evaluations, ten structures were selected for a subsurface evaluation. The results of the research clearly identify the dominant modes of pipe-arch structural deterioration and/or failure. Appropriate recommendations are presented for significantly reducing and/or eliminating these deficiencies in future procurements of corrugated metal pipe.
