DRC1, the additional overturning moment is anoter reason why I am not sure it is a good idea to allow the light pole to tilt.
tdunaway, AASHTO also says to use Broms Method for preliminary analysis only. That is one reason why I used L-Pile to compare the results. However, when using L-Pile I...
From the previous two post, it sounds like a short shaft is okay to use in this situation.
My concern about using a rigid, short shaft is that the foundation will rotate and the light pole would be tilted. Based on the LPile model, the foundation will rotate about a single point and tilt like...
I realize the diameter of the shaft makes it rigid and I am not putting in any inflection points.
If the shaft is made long enough, then it will bend before the soil at the base of the shaft yeilds and there will be zero deflection at the base.
Is this a necessary requirement for a foundation...
I am designing a drilled shaft foundation for a high mast lighting tower. There are some differing opinions around the office about the required shaft length and I am seeking some more opinions.
The HML tower is 120' tall and the soil is sand with phi = 0.33. The applied service loads at the...
