Bridge Pier Pile Cap Top Steel
Bridge Pier Pile Cap Top Steel
(OP)
I know it isn't common practice to connect column steel to cap top steel. Aside from the dowels that actually extend most the time to the bottom steel in the pile cap, how does a "fixed base" pier transfer its moment to the concrete pile cap. I would think this concentrated moment would create tension on the top surface of the cap near the perimeter of the pier column. I also have down drag on the piles.
Does anyone have insight on this?

Thanks for your response. Neglecting pile drag down for now. Does the moment from a column at the top of the cap create tension at the top of the cap at or near their interface?

RE: Bridge Pier Pile Cap Top Steel
I've had a bit more time to think about this. The dowels anchor the tensile forces from the column vertical bars. This, in effect, accounts for the moment from the pier. Thus no tension in the top of the cap unless the cap is not thick enough or the dowels and its surrounding concrete result in anchorage failure.
I think I've answered my own question.
Thanks again.
