Axial and Lateral Load Testing of Steel Fin Pile Foundations-PPT Presentation

PPT Presentation

Pdf Summary

The study evaluated the axial and lateral load capacity of steel fin pile foundations for a design scenario involving a 35-foot light pole. It also examined whether pile performance changed when lateral load was applied at different points and compared field measurements with pre-installation modeling.<br /><br />Two fin piles were installed using a vibratory hammer, with each installation taking about 15 minutes. The piles underwent axial and lateral load tests; one also received a dynamic load test. Testing followed relevant ASTM procedures. Lateral behavior was measured using a shape array, and the results were compared with modeled performance and conventional pipe piles.<br /><br />The results indicated that fins increase both lateral and axial resistance compared with a pipe pile without fins. The study also found that fin orientation matters: piles should be positioned with the anticipated direction of maximum lateral load between the fins. Steel fin piles were shown to be quick to install with the equipment used. Further work was planned to improve the modeling aspects of the analysis.
