Flagpole footing design

This calculator will determine the Flagpole Base Design requirements per IBC and UBC. HEIGHT OF POLE ABOVE GRADE, H = 62. The course is designed to help . Ground Set installations are the strongest and most common form of flagpole installation.

All standard Flagpoles shown on this site are designed for Ground Set foundations.

Minimum Embedment Guide - Round.

On the inside, at the bottom, steel wedges are welded to center the pole upon installation.

This module determines actual soil pressures and required depths for pole footings primarily supporting lateral loads. Such footings are commonly called flagpole footings . Other materials might offer an advantage in certain specific conditions but in general, aluminum will last longer and age more gracefully that steel, fiberglass, concrete or wood. Our design formulas, using the relationship between flagpole height, base diameter and base wall thickness take into consideration the components . Foundation tube shown has lightning ground spike attached to base - plate thus allowing lightning charge to pass directly through concrete footing into soil under foundation. Typically the design for the foundation is done at the same time by the same engineer. Sometimes the flagpole type footings may be backfilled with concrete or other fill.

In greenhouse design , flagpole type footings are usually designed as unrestrained foundations. Ensure the site is safe to work, cone off working area if necessary. Mark out and dig the foundation. Once the hole is complete put the bottom part of the hinged base or ground socket in the hole.

Shoe Base installations are typically used when an above ground installation is required. Contact American Flagpole Customer Service for Wind Speed information for your particular design. Back to Instruction INSTALLERS TAKE NOTICE!

Overhead electrical lines, buried utility cables, and natural gas lines pose situations that require EXTREME CARE DURING INSTALLATION of foundation and flagpoles. Dig hole approximately as shown on chart. A standard feature for most roadside flag or banner poles. The pole is likely to dislodge from its base . The design must include calculations for the foundation and strength of the pole (including any connections).

Material specifications must be provided. In other words, a 30' flagpole is really 33' overall putting 3' of the pole in the ground. Pole Foundation Design with Spreadsheet.
