Helical Piles and Tiebacks Committee – Analyzing shake table testing conducted on helical piles (see p. 117). DFI committee members and other industry partners are contributing funds to support this five- phase helical seismic research project being conducted by Professor Amy Cerato of University of Oklahoma. The project began in 2015 and is intended to study the performance of helical piles under seismic loading conditions.

Phases 1 and 2 have already been awarded, including a detailed literature search and large-scale shake table tests conducted at the University of California, San Diego. DFI’s contribution will fund part of Phase 3, which will include the analysis of the shake table tests. The deliverable will include a design report with readily implementable recommendations. Funding amount: $20,000.
