Seismic Mass of Pipe Piles in Water
Seismic Mass of Pipe Piles in Water
(OP)
I have a situation where I'm analyzing a bridge bent that includes open-ended pipe piles driven through water. Would the water within the pile be included in the seismic mass of the structure? I'm inclined to say yes but can't find any explicit guidance on this matter. Note I'm considering this a separate issue from hydrodynamic mass.
Thanks!
Thanks!

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

You'd presumably have some effects from the water outside, and might have some effective mass from water outside the pile as well.

On the face of it, that would seem to be a conservative approach unless you get resonance between the structure period and the waves.
Without simplification, I can't picture a good way to actually model the situation. It seems like there would be too many different parts to get a good picture of the real behavior.
