INSTRUCTOR:
Naresh Samtani, Ph.D., P.E., D.GE, F.ASCE
Purpose and Background
Using a collaborative and interactive learning approach, this virtual workshop will help you understand the design and construction aspects for soil nail walls. You will learn newer design approaches based on the LRFD platform that is the basis for guidelines for soil nail walls by the American Association of State Highway and Transportation Officials (AASHTO) and the Federal Highway Administration (FHWA). The workshop will help you assimilate the design and construction aspects through active participation by frequent interactions throughout the workshop and real-time expert feedback. The interactions will facilitate a better understanding of the nuances of the newer design principles which would help you avoid costly design errors in real-world projects. In between the two live sessions, attendees will independently work on an application (e.g., exercises) or a reflection (e.g., reading) assignment.
Benefits and Learning Outcomes
Upon completion of this course, you will be able to:
- Become familiar with the latest limit state design approaches and standards for soil nail walls
- Avoid common pitfalls and costly errors in analysis and design
- Be able to categorize and streamline limit state evaluation
- Recognize the importance of considering construction as part of overall design process
- Explain the terminology for soil nail walls
- Explain design of soil nail walls using principles of limit state design
- Explain the essential elements of construction
- Recognize construction procedures and influence on wall design and performance
- Explain the importance and concepts of nail testing
- Identify necessary characteristics of software tools
- Explain corrosion considerations
- Discuss facing (shotcrete) analysis
- Identify the necessary information on plans and specifications
Assessment of Learning Outcomes
Students' achievement of the learning outcomes will be assessed via a short post-assessment (true-false, multiple choice and/or fill in the blank questions).
Who Should Attend?
Geotechnical, Structural, Architectural, General civil engineering, Excavation support, grade separation cut earth structures

How to Earn your CEUs/PDHs
This course is worth .4 CEUs /4 PDHs. To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 30 days of the course.
How do I convert CEUs to PDHs?
1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
