Does anyone know how to estimate the forces imparted to a bridge pile bent due to waves under hurricane winds?

Forces can then be estimated for a design wave height. Will depend on pile/pier diameter, primarily. The "Shore Protection manual" by the Corps of Engineers will cover all this.

M^2, I'd be interested in that Nafac publication if you find it ---- CarlB, I'll try to obtain the C of E publication on shore protection. Thanks for the tips.
Ron, I did back into the number and that's what jolted me.
This is a frame consisting of two 24" sqr prestressed piles connected at the top by a tie beam such that a full moment connection is developed there. I chose a point about ten feet below the sea bottom that would approximate the maximum moment developed in the pile and backed into the load that would be required near the top to simulate the force imparted to it by the wave action.
The result was a load that was less than 1/3 of the number that appeared on the original design drawing, leading me to question how that number was arrived at originally. In this case, "originally" means 1959.

RE: Forces due to ocean waves in high wind
Your number might be closer than you think, since the wave action likely caused some scouring, thus fixity would be achieved at a lower depth than was perhaps considered in the original design.
Is the actual water depth the same now as when they were constructed? If so, is it possible that fixity was considered in the original design to be higher than we would currently.

I assumed "bent" was used to describe a structural member/shape, rather than past tense of "bend".

And thanks for the lecture info. I downloaded the ppt presentation and will take time to absorb it later. Looks like just what I need.
Many thanks.

Did you put up the palm tree this year?!
The way the weather is in the central midwest, the snow is only a figment of my imagination and so is the fact that I've walked uphill to and fro school. If I tell that story nowadays, I get strange looks and not for the obvious reason. It's all that hot-air from politicians causing midwest warming!

Dik, what articles are you refering to, the same ones that were mentioned above in this thread, or something else?
I really appreciate you guys responding to this.

I often do that when I get a good link... sometimes even end up in the directory with more stuff...

Sounds like you have solved your problem though. Good luck.

Many thanks to all of you for inundating me with all this valuable info.
Looks like it's back to school again for a while.
