Piles in most cases are fixed head as they are terminated at a pile cap that
prevents rotation of the head of the pile. Free head piles are useful in
certain circumstances, but are very difficult to achieve in a pile cap - the
reinforcement connecting the pile to the cap needs careful detailing to
ensure that pile head is free to pivot about the head - which I think is
referred to as a pinned connection in structural engineering.

Subject: when you consider a pile fixed at head?
In designing a pile for lateral loads, there are two cases for pile head:
one is free head and the other is fixed head. There is a great economy in
designing a pile with fixed head. But I didn't see anywhere criteria for
considering a pile fixed at head. Any help in finding a reference that
explains the conditions for free and fixed head is highly appreciated.
