Abstract:

Pipe piles are used extensively for bridge substructures in Tennessee. This research serves to develop a systematic approach to the selection and the design of pipe pile-supported substructures, both piers and abutments. Included are both a design manual and design examples, for the design of three pipe pile-supported pile bents: (1) pipe pile bents with a concrete plug connection to the cap, (2) concrete-filled steel tube (CFST) pile bents with the pile embedded in the cap beam, and (3) reinforced concrete filled steel tube bents with a gap between the top of the pile and the cap beam. Appropriate strain limits are incorporated in accordance with the latest science. Also included is discussion on the implications of modification to current TDOT field verification of pile capacity using dynamic testing rather than static load tests. Updated spring constants for pipe pile-supported integral abutments and updated point-of-fixity estimates are included in the study. Finally, a critical assessment of current corrosion-protection measures has been carried out.
