TECHNICAL PRESENTATION TOPIC – LRFD FOR MICROPILES (1 PDH)
Speaker: Jonathan Bennett, PE, D.GE

Load and Resistance Factor Design (LRFD) is the predominant design method utilized today for reinforced concrete and structural steel, and is the primary focus of the AASHTO LRFD Bridge Design Specifications. Historically, micropile design has been performed mainly with Allowable Stress Design (ASD) methodologies, and most of the micropile design manuals and specifications in existence prior to 2008 were based on ASD.

In light of this history of ASD design methodologies, and in spite of the widespread use of LRFD in general structural design disciplines, there have been a number of questions and a great deal of confusion regarding the proper use and implementation of LRFD design methodologies for micropiles. The author, as part of a DFI / ADSC Joint Micropile Committee initiative, developed a presentation in response to these questions and issues which covers the fundamentals of LRFD as it applies to micropiles, and provides an illuminating comparison with ASD methodology.

This paper is a formalized and updated snapshot of the current State of Practice of LRFD for Micropile Design based on the most current information and design codes relevant to micropiles. It will describe the fundamentals of Load and Resistance Factor Design (LRFD), demonstrate micropile design and testing utilizing LRFD, compare the results with historical ASD design, point out the limitations of current LRFD practice relative to micropiles, and finally map out the path forward with regard to proper implementation of LRFD as a true reliability based design methodology for the design of micropiles.

DFI Super Pile 2013 Conference – Invitation to Speakers

Wednesday, May 15 – Thursday, May 16, 2013
Hilton Minneapolis
Minneapolis, MN, USA

Seven of DFI’s technical committees have joined forces to organize this year’s Super Pile Conference. This two-day conference will consist of presentations on the latest developments in: Driven Piles, Augercast Cast-In-Place / Drilled Displacement Piles, Micropiles, Marine Construction, Testing and Evaluation of Foundation Systems, Seismic Design and Drilled Shafts. Day One will be a plenary (combined) session and Day Two will have two concurrent sessions giving attendees the option to choose which presentations are of interest to them.

Presentations will focus on local and out-of-state case studies, historical development, theory and design with emphasis on practical application, new technologies and ides for future development. There is particular interest in presentations addressing challenges for deep foundation construction in cold weather environments. Equipment, material and instrumentation suppliers, contractors and other vendors will present their services in our Exhibit Hall. Visit www.dfi.org for for up-to-date details on this conference.

PROPOSAL SUBMISSION
SuperPile 2013 is soliciting presentations in the following areas:

  • Augered Cast-In-Place and Drilled Displacement Piles
  • Drilled Shafts
  • Driven Piles
  • Marine Foundations
  • Micropiles
  • Seismic Design
  • Testing & Evaluation

Potential Speakers for SuperPile 2013 should submit a brief abstract (no more than 300 words) describing the subject matter of their proposed presentation. In addition, include the committee which should review your abstract, the presentation title and the speaker name within the abstract document. The due date for abstract submissions is Friday, December 21, 2012. Please email proposals to Erin Groenewal at events@dfi.org.

Notification of acceptance or declination will be returned to all authors no later than Monday, January 28, 2013. Guidelines for presentation development will be provided to all accepted speakers at that time. They will be required to commit to presenting their topic on Wednesday, May 15th or Thursday, May 16th and to submit a PowerPoint presentation to be included in the conference publication by Friday, April 5, 2013. Also, all accepted authors should consider developing their abstract into a technical paper for consideration by the editors of the DFI Journal for inclusion in a future volume.

Small Diameter Geo-Support Design and Construction Seminar

Registration is now open for the ADSC / DFI Small Diameter Geo-Support Design and Construction Seminar!

The Small Diameter Geo-Support Design and Construction Seminar is a two-day event that will cover aspects of both anchored earth retention and micropile foundation support from a perspective of design, construction, and case history coverage. The seminar will feature presentations from leading North American and worldwide experts on the design and construction of small diameter geo-support systems. This practice-oriented seminar will be valuable to owners, engineers, architects, general contractors, and others in terms of understanding the fundamentals, applications, design, and construction of small diameter ground anchors and micropiles for earth retention and foundation support applications. There will be opportunities for networking and individual discussion with the panelists and presenters throughout this two-day event.
