Cross-USA Lecture: "Evaluation of Axial Pile Response for Load-Displacement-Capacity and Load Transfer Using Seismic Piezocone Tests" presented by Dr. Paul Mayne, PhD, P.E.

Please join us for the Geo-Institute's Cross-USA Lecture tour stop in Central Florida. The ASCE's Geo-Institute provides the Cross-USA Lecture Tour to local G-I chapters as an ongoing program to enhance the prestige of the geoprofession. Each year a distinguished geoprofessional is selected to deliver the lecture at selected locations across the USA. This year's lecturer is Dr. Paul Mayne, PhD, P.E. from the Georgia Institute of Technology.

The event will take place at the University of Central Florida Fairwinds Alumni Center on Thursday January 31st, 2019. A social/cocktail hour will take place from 6:00 to 7:00 pm followed by dinner and lecture presentation from 7:00 to 8:30 pm. All professionals and college strudents from the Central Florida area are invited to attend. Please read below for addtional event information. 

PRESENTATION TOPIC:

For deep foundations, cone penetrometer (CPT) and piezocone (CPTu) data can be used in either traditional bearing capacity solutions via interpreted geoparameters, or alternatively with direct-CPT methods that scale the measured cone tip resistance and sleeve friction to unit end and unit side resistances of the full-scale pile foundation. A Modified Unicone Method is presented based on 330 pile load tests, compared with 105 load tests for the original Unicone Method.  With seismic piezocone tests (SCPTu), the small-strain stiffness (G₀) is obtained from the shear wave velocity measurement.  A modulus reduction curve can be expressed in terms of the mobilized load (Q/Q_ult) which is in essence, the factor of safety.   Introducing closed-form elastic solutions for axial pile displacement and load-transfer with depth, the use of SCPTu permits a construction of the load-displacement-capacity curves and axial load distribution for driven, jacked, and drilled pile foundations. Case studies from South Carolina, Georgia, British Columbia, Texas, Alabama, and Alberta are presented.

LECTURER'S BIO:

Paul W. Mayne. P.E., PhD, is a professor of Civil & Environmental Engineering at the Georgia Institute of Technology. With 42 years in geotechnical engineering, Paul is an expert in geotechnical site characterization, particularly the cone penetrometer, piezocone, dilatometer, and seismic tests with applications to foundation systems and ground modification.  He has published 330 technical papers and participated in 120 short courses. Of recent, Paul authored the 2007 Synthesis 368 on Cone Penetration Testing (www.trb.org), co-authored the SOA-1: Geomaterial Behavior & Testing at the 17^th ICSMGE in Egypt in 2009, gave the ASCE SOA lecture on In-Situ Testing (GeoOakland 2012), 16^th Sowers Lecture (2013), 12^th Jennings Lecture in South Africa (2014), James Hoover Distinguished Lecture at Iowa State Univ. (2014), invited keynote KN2 at CPT’14, 2014 Hal Hunt Lecture at the 39^th Annual DFI Conference, invited keynote at ISC-5 Brisbane (2016), Nonveiller Lecture in Zagreb (2016), 34^th Manuel Rocha Lecture in Lisbon (2017), the Spencer Buchanan Lecture for 2018, and ASCE G-I Cross-USA lecture for 2018-2019. He was selected as a GeoLegend by GeoStrata (2016). Dr. Mayne is an active member of ASCE, TRB, DFI, ADSC, CGS, USUCGER, and ISSMGE, and served as chair of the international committee on in-situ testing (TC 102) from 2000-2013 and ISSMGE Vice President for North America from 2013-2017. Of additional note, Paul has worked as a consultant on recent projects in Australia, Virginia, Washington, South Carolina, Ontario, Puerto Rico, Alabama, Georgia, Belgium, North Carolina, and Alaska.
