Axial Design and Post-Grouting in Drilled Shaft Foundations (Ohio Timed & Monitored Video)

In Axial Design and Post-Grouting in Drilled Shaft Foundations , you'll learn ...

• Axial load behavior in drilled shafts, including side and base resistance mechanisms
• What post-grouting is, why it's used, and how it can significantly improve base resistance and reduce settlement
• Grout materials, tip grouting systems, performance improvement mechanisms, and design methods
• Construction challenges and termination criteria to help you anticipate and mitigate potential issues in the field

Overview

To meet the Ohio Board's intent that online courses be "paced" by the provider, a timer will be used to record your study time. You will be unable to access the quiz until the required study time of 105 minutes has been met.

Drilled shafts are widely used for deep foundation systems, and their performance under axial loads is a critical component of safe and efficient design. This course was developed to provide engineers with a practical understanding of axial load behavior in drilled shafts, including side and base resistance mechanisms. It introduces LRFD concepts, resistance factors, and design methodologies.

In addition to design fundamentals, this course explores the increasingly popular technique of post-grouting to enhance shaft performance. Participants will learn what post-grouting is, why it's used, and how it can significantly improve base resistance and reduce settlement. Detailed discussion is included on grout materials, tip grouting systems, performance improvement mechanisms, and design methods. Construction challenges and termination criteria are also addressed to help engineers anticipate and mitigate potential issues in the field.

Tailored for all professional engineers, this course also benefits builders, architects, project managers, quantity surveyors, QA professionals, academics, and students. Whether you’re starting your career or an experienced professional refreshing your knowledge, this course delivers the tools and insights needed to succeed.
