In this session, foundation design for pole structure based on the International Building Code (IBC) Method is explained.
Flagpole, traffic sign poles, light poles, etc. are some examples of structures who are being supported on pole foundations.
Pole foundations are generally drilled shaft, bored pile or caisson foundation types. The lateral loads on pole foundations are more significant compared to the vertical loads.

thank you for this awesome video. The total applied base shear in your calculations is not correct.

Thanks a lot for your comment. The focus on this session is not shear calculation on the pole, it is more about sizing the concrete shaft, but out of curiosity, why do you think the base shear is not correct?

How were forces on pole, arms, and light fixtures calculated?

Thanks for you comment. I hope the presentation was useful. The loads have been calculated in accordance with the IBC standard. The details of load calculations was not provided as it was of secondary importance to the main goal of the presentation which is the foundation design based on the IBC.

Hello, The forces on the pole and its appurtenances should be calculated based on respective effective projected area (EPA) and the shape factor (Cf) for each item, the resulted area (m2) multiplied by the velocity pressure (KN/m2) shall give you force (KN).

Thank you for the video, very nice way to explain it. Can you please suggest how you design anchor bolts connection for the same structure instead of embedding pole inside the concrete?

I am glad you liked it. Anchor bolt design for the poles is very similar to AB design for columns base plate with overturning moment. You can simply calculate the tensile force in the anchor bolts by dividing the overturning moment by the AB spacing. It is a bit conservative, but simple and easy. Then you can calculate the required AB size and development length based on the calculated tensile force.

Please provide design for foundation element itself. What should the reinforcement design be based on? Between D/3 to 2D/3?

thanks for your view and comments. The focus on this session was on the sizing of the drilled shaft. we will provide more contents on the structural design of the shaft itself.

The shear value is correct, but the placement must be at the base of the pole.

The total shear force will be transferred to the concrete shaft at its connection with the pole, right on the top.

thanks FOR YOUR VIDEO, It is very Useful, May ask foundation for imbedded Poles is it required Top reinforcement??and COde reference pls if available?

thanks for your comments. I am not sure if I quite understand your question. what do you mean by top rebar?
