lpile question
i am getting very large negative deflections for my pier lpile runs when using a pinned head connection (hpile will be encased in concrete approx. 22ft above ground surface).  can i use a fixed-head connection in this case.  if i use a pinned head connection, what could i use as a control option, how much deflection should i allow?   
(hpile will be encased in concrete approx. 22ftfff"> above ground surface)
how could it be pinned?
how much is the embedment length of the pile (into concrete)?
embedment 22 ft into concrete.   
sorry, i was unclear, it will be encased in the concrete from ground surface to 22 ft above ground surface.  so fixed head then?
fixed.
reason: the angle between the pile and the bottom face of the mass concrete will stay constant.
thank you very much
my pleasure, if that solves your problem.
