Stream Force on Bridge Piers and Abutments
Stream Force on Bridge Piers and Abutments
(OP)
On AASHTO 17th Ed Section 3.18.1.2 the code tells "When the direction of the stream force is other than normal to the exposed suface.....the effects of the directional components of stram flow pressure shall be investigated."
My question is: How do you define expose area, area perpendicular to the flow of the member or area along the member?

However, I would not forget about the instance of logjambs at the piers during high runoff. I've seen it happen and often. That will substantially increase the lateral load to the piers.
