INSTRUCTOR: Alexander Newman, P.E., F.ASCE

Purpose and Background

The first part of the seminar explores the complexities of designing anchor bolts embedded in concrete, which used to be uncomplicated. The building codes contained simple design formulas, and the procedures were straightforward. Today, the International Building Code (IBC) references ACI 318, which covers the design of embedded anchors in Chapter 17 (formerly Appendix D); IBC further modifies some of its provisions. The design procedures of ACI 318 are rather complex and difficult to follow. Since the introduction of ACI 318 Appendix D in 2002, some of its provisions continued to change, attesting to a rapidly evolving state of the art on this topic. Many challenges have been reported in trying to use the procedures of ACI 318 to design anchor bolts for shear and tension in practical applications. Also, ACI 318 does not address the complex behavior of anchor bolts above the top of concrete, which might control their capacities.

The difficulties of meeting the new code provisions are particularly acute in metal building systems, where the primary frame columns often exert large lateral and uplift reactions on the foundations. The traditional anchor bolt designs that have  been used in these common structures for generations no longer conform to the current code requirements. In many cases, other concrete embedments must be used instead, but these are often unfamiliar to many designers and contractors. The presentation provides an in-depth coverage of the new methodologies and explains how they affect the traditional construction practices of anchor bolts. Many design examples immediately useful in practical design illustrate the discussion.

The second part of the seminar is devoted to the design of foundations to resist horizontal and uplift forces. Such foundations are often needed for buildings with  rigid-frame-and braced-frame and many nonbuilding structures such as transmission towers, light poles, and sign supports. The uplift forces could also control the foundation sizes of many other lightweight structures - a situation rarely discussed in the engineering schools and textbooks. The seminar fills the knowledge void by exploring the most common design solutions for such foundations.

The third part of the seminar covers strengthening existing anchors, embedments, and foundations to resist horizontal and uplift forces. The audience is encouraged to ask questions throughout the presentation, and the seminar concludes with the final Questions and Answers opportunity.

Seminar Benefits

• Explore the complexities of anchor bolt design, including the design provisions of ACI 318 and other specialized standards and publications. Find out which long-used practices for frame anchorage in pre-engineered metal buildings need to be changed.
• Work through a number of design examples illustrating practical solutions for today's code
  requirements
• Find out how to design foundations for the forces of wind uplift
• Examine the design methodology for various types of foundations subjected to horizontal column
  reactions
• Learn about the effects of column base fixity on foundation design

Learning Outcomes

Upon completion of this course the participants will be able to design anchor bolts, embedments, and
foundations to resist horizontal and uplift column reactions. The instruction will utilize a
combination of lecture, working through many design examples, answering questions, and refreshing the
discussion through a short post-seminar exam.

Assessment of Learning Outcomes

Students achievement of the learning outcomes will be assessed through a series of problem-solving
design examples, class discussion during the presentation of each major topic, and case studies.

Special Feature

Each participant will receive a copy of the book Foundation and Anchor Design Guide for Metal Building
Systems by Alexander Newman (McGraw-Hill, 2013).

Who Should Attend?

Structural and civil engineers seeking to broaden their knowledge of designing anchors, embedments,
and foundations to resist horizontal and uplift forces. Despite the technical topic the instruction is
kept enjoyable and easy to follow.
