Project Summary

This project, a joint effort between UAF and the University of Arkansas, developed design guidelines for using screw piles as a cost-effective deep foundation alternative to conventional pile structures in northern regions. Additional tasks included establishing a database for dynamic properties and cyclic behavior of cold region soils under seismic loading conditions, providing seismic design recommendations for deep foundations in cold regions, and supplementing current foundation seismic design codes. Researchers performed surface wave testing at 30 sites in Fairbanks, Alaska. This project was discontinued in 2010, upon the PI's departure from UAF. AUTC is seeking an effective forum for the collected data.
