DFI Helical Piles & Tiebacks Seminar September 18-19 in Montreal, QC Canada
by Bill Bonekemper
The Deep Foundations Institute (DFI) Helical Piles & Tiebacks Committee (HPTC) will be hosting its annual specialty seminar on September 18-19 in Montreal. This year’s seminar theme is Design and Installation of Helical Piles and Tiebacks for New Construction and Rehabilitation. Program coordinator, Yasser Abdelghany, Ph.D., P.Eng, has assembled speakers with extensive experience in designing helical pile and tieback configurations for testing the effects of seismic loads.
Dr. Amy Cerato, University of Oklahoma, will be making a keynote presentation on the results of seismic shake table testing of individual helical piles and pile groups in sands. The testing was conducted at the University of California San Diego Shake Table testing facility in February, 2016.
Dr. Abdelghany, Ministry of Transportation & Infrastructure and University of Victoria, will be presenting on the behavior of reinforced grouted and fiber reinforced grouted shafts helical piles seismic performance.
Dr Cristina de H.C. Tsuha, University of Sao Paulo, will be presenting on centrifuge modeling of the behavior of helical foundations subject to tensile cyclic loading.
Dr. Hesham El Naggar, University of Western Ontario, will be presenting on the dynamic behavior of helical piles.
These are but a few of a great lineup of presentations for this year’s seminar.
Oh Know - Final Edits are Due Now!!
One other important event planned for the seminar is the preview of the first edition of a helical pile foundation design guide - “Design and Construction of Helical Pile Foundations” - a document developed by team members from the HPTC. Wayne Thompson, P.E., CTL/Thompson Fort Collins, CO, is the team leader of this project, and a draft of the design guide is out for final editing as of this writing. This is a much-anticipated and much-needed publication for the helical pile industry that has been under development for over two years.
