Pole Foundation Design with Spreadsheet

John W. Andrew, P.E.


Course Outline

This course highlights the requirements for determining the embedment depths required and foundation pressures for pole foundations for signs, flagpoles, light poles and pole framed buildings in accordance with Section 1804 and Paragraph 1805.7 of the 2006 International Building Code.  The course is designed to help architects and structural engineers become familiar with the design criteria for pole foundations.  A copy of the 2006 International Building Code is required for this course.  A downloadable Excel© spreadsheet is provided to assist with the calculations. 

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

Learning Objective

At the conclusion of this course, the student will be able to determine:

Intended Audience

Structural Engineers, Geotechnical Engineers and Architects.

Benefits to Attendee

The Attendee will learn how to determine the embedment depths and foundation pressures for many pole type structures, including signs, flagpoles, light poles and pole framed buildings.  These pole foundations may be more efficient and easier to install than conventional spread footings in many applications.  

Course Introduction

Poles foundations are commonly used for sign, flagpole and light pole foundations and pole framed buildings.  A design criteria for pole foundations is indicated in Section 1804 and Paragraph 1805.7 of the 2006 International Building Code.  This criteria applies to vertical poles considered columns embedded in either earth or in concrete footings in the earth and used to resist lateral loads.  The backfill in the annular space around a column that is not embedded in a concrete footing shall be clean sand thoroughly compacted by tamping in layers not exceeding 8 inches in depth.
