Development of an Innovative, Partially Prestressed Concrete Pier Concept to Enhance the Durability of U.S. Navy Piers
Bibliographic record
Abstract
A majority of the active waterfront structures used by the U.S. Navy were constructed more than 50 years ago. In many of these structures, concrete damage due to corrosion of reinforcing steel has resulted in significant costs for maintenance and repairs. The Naval Facilities Command (NAVFAC) Engineering and Expeditionary Warfare Center (EXWC) conducted a multi-year research project funded in part by the Office of Secretary of Defense (OSD) Corrosion Protection and Control (CPC) program with a goal of developing a prototype fully prestressed concrete pier design with the same features as the recently constructed Pier 12 at Naval Base San Diego that would minimize concrete cracking to produce more durable Navy piers resulting in a significant reduction in maintenance and replacement costs for the Navy waterfront inventory. Pier 12, primarily used to berth aircraft carriers, consists of a 2-foot-thick (0.6-meter) reinforced concrete flat slab deck supported on 2-foot (0.6-meter) prestressed concrete piles spaced at about 20 feet (6 meters) on center each way.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
