Axial Design and Post-Grouting in Drilled Shaft Foundations (Webinar)

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

---

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 webinar 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, the webinar 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 webinar 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 webinar delivers the tools and insights needed to succeed.
