Purpose and Background

With the introduction of ACI 318 Appendix Din 2002 (now ACI 318 Chapter 17), the design of anchor bolts has become complex and challenging. The difficulties of meeting the new code provisions are particularly acute in the design of metal building systems and other structures that use rigid frames. The columns of these structures tend to exert large lateral and uplift reactions on the foundations, yet the typical anchor bolt spacing and edge distances are rather small. For decades, these column reactions were assumed to be resisted by anchor bolts designed for shear and tension loading, but the provisions of ACI 318 make this practice difficult to justify without profound changes in the design and construction of embedded anchors.

This webinar explores the complexities of the new design methodologies and explains how they affect the traditional practices of designing and placing anchor bolts. The design examples illustrate the discussion. The audience is encouraged to ask questions throughout the presentation, which concludes with the final Questions and Answers opportunity.

Benefits and Learning Outcomes

Upon completion of this course, you will be able to:

• Analyze the complexities of today's code provisions dealing with anchor bolt design, including those of ACI 318 Chapter 17 (formerly Appendix D)
• Evaluate which long-used practices for frame anchorage in pre-engineered metal buildings may need to be changed
• Review the available options for meeting today's code provisions in structures where the column reactions include high horizontal and vertical uplift forces
• Examine design examples illustrating practical solutions for today's code requirements
• Understand why the decades-old practices for designing anchor bolts are no longer appropriate and why new design solutions are needed
• Summarize contemporary methods of designing anchor bolts for shear and tension

Assessment of Learning Outcomes

Students' achievement of the learning outcomes will be assessed via a short post-assessment (true-false, multiple choice and fill in the blank questions).
