Post-tensioned splice system for precast, prestressed concrete piles: Part 3, capacity verification from laboratory and full-scale testing

摘要

This is the third of three papers describing the development of a new post-tensioning system for splicingprestressed concrete piles. The first paper coveredconceptual design of the proposed system and the development of its component parts.1 The second paper presentedfindings of a side-by-side comparison of the field drivingperformance of a full-sized, 100 ft (30 m), post-tensioned,spliced pile with that of a similar one-piece, unspliced pile.2This paper describes how the system for fabricating laboratory and full-sized spliced specimens was implemented,as well as how testing was performed to verify bendingcapacity.
