LRFD for Geotechnical Engineering Features - Micropile Foundations

*Open only to Central Ohio Section Members
*Seating is limited to the first 25 people
*Bring your own lunch

Purpose and Background
This webinar concentrates on micropile foundations. Micropile foundations are often a technically sound and cost-effective foundation choice where a deep foundation solution is appropriate based on site conditions, applied loads and project schedule and performance requirements. The LRFD platform offers a rational framework for consideration of micropile foundation systems. The webinar will use the American Association of State Highway and Transportation Officials (AASHTO) LRFD Bridge and Structures Specifications as a basis for the technical content. Applicable articles in Section 10.5 and 10.9 of AASHTO LRFD Specifications will be used as a basis of discussion.

The webinar will include discussion on the terminology and construction of micropiles, identification of limit states and resistance factors, axial compression and uplift resistance of a single micropile, estimation of grout-ground bond resistance and tip resistance, group efficiency factors for evaluation of axial resistance of micropiles in groups, buckling and lateral stability, lateral resistance of micropiles in groups, evaluation of settlement of micropile groups, concept of cased, uncased and plunge lengths, consideration of extreme event limits state such as scour and seismic events, corrosion and deterioration, and typical structural detailing and design. The webinar will assume that the participant has a basic working knowledge of design and construction of deep foundations.

Learning Outcomes
This webinar will help participants analyze and size micropile foundations using the LRFD approach.

Webinar Benefits

• Learn basics of LRFD-based analysis of micropile foundations
• Continue building on the knowledge gained from previous LRFD webinars
• Examine the possibilities and benefits of improved communications between geotechnical and structural specialists for micropile foundation design

Intended Audience
This webinar should benefit geotechnical and structural specialists as well as general civil engineering designers involved in the analysis and design of micropile foundations. General and specialty deep foundation contractors can also benefit from the webinar. Basic knowledge of LRFD and geotechnical principles is a prerequisite. The webinar will benefit professionals with 0 – 25 years of practical experience in analysis/design and construction of micropile foundations.

The Central Ohio Section of ASCE sponsors free continuing education webinars as a service to our members. These webinars are produced by ASCE and normally cost $250 or $300 for ASCE members. However, the Central Ohio Section is paying the registration fee and inviting any interested section members to attend for free. Just RSVP by the deadline. Seating is limited, so do not delay.

You can see the complete list of webinars available from ASCE National on their website. If you see one you like, let us know. If you and your company would like to host one, let us know that too. If you open it up to any interested Central Ohio ASCE section members to come, we will pay the registration fee.
