Full-Scale Field Investigations and Numerical Analyses of Innovative Seismic Composite Fiber-Reinforced Polymer and Reinforced Grouted Helical Screw Instrumented Piles Under Axial and Lateral Monotonic and Cyclic Loadings
Bibliographic record
Abstract
The axial and lateral monotonic and cyclic behaviors of helical pile foundations were investigated and new innovative helical screw systems suitable for seismic loadings were developed and patented. More than 100 full-scale field load tests were conducted on instrumented helical screw piles installed in cohesive soil. The piles included: plain helical screw piles (P-HSP); grouted (G-HSPs); fiber-reinforced polymer FRP-G-HSPs; and reinforced grouted RG-HSPs. The RG-HSP piles' axial capacity was more than twice that for P-HSP with minimal reduction after cyclic loading, and their lateral capacity was more than 3 times the P-HSPs capacity. A 3-D finite element model was established. The results of 3-D finite element modeling were used to establish the load transfer mechanism and a design methodology for the considered piles.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
