So, if we are only talking about t-direction, it should not have anything to do with the v-direction loading, right? The torsion resistance should only depends on your side friction in t-direction.
Hi, HTURKAK, if we are now only considering the torsion/twisting of the pile, should we subtract the vertical loading/shaft weight from the skin resistance, that's the question I want to know. Thank you.
Thank you, ANE91.
I am actually pretty familiar with these methods that different DOTs use. These are all methods to get the ultimate torsion resistance, but none of them addresses the details in design. I am assuming the axial load is not subtracted from the ultimate resistance.
Thank you, HTURKAK.
I understand your model. But, in geotech, we usually just take the approach of getting a total skin friction, uniformly along the shaft surface.
The approach comes with a unit skin friction/pressure, which catches the vertical earth pressure already. Then times the shaft...
Hello,
I have a question regarding the geotechnical torsional resistance of a drilled shaft.
After calculating the skin friction (force), do we need to subtract any axial loads (shaft self-weight and any applied loading on top) to get a net resistance force, and then use this force time shaft...
