COLUMN TENSION LOADS APPLIED TO PILE CAPS
(OP)
Is there a method or parameter of reinforcement to be applied on pile caps that are under tension loads??
the theory always induce that the pilecap is in compression load applied by the column or wall that is on it.
Also, I've seen that some persons use some reinforcement on the top of the pilecap, this reinforcement is additional to the typical bottom reinforcement of the pile cap. They also use closed stirrups both ways on the pile cap.

In general, pile anchorages are designed to resist 10% of the ultimate strength (0.1xAxFy) in tension. Thus any anchorages (for steel piles) or reinforcing (for concrete piles) should meet this requirement. Also, for concrete piles, AASHTO, recommends that at least four dowels with a minimum reinforcing ratio of 0.01 be embedded in the pile cap.
As for the top mat of steel in the pile cap, it is generally a reflecion of the bottom mat for convienence in lower seismic zones. In moderate to high seismic zones one should check the top mat against the tension loads developed in the pile just as one would design the bottom mat based on compression in the pile.

I hate to use that argument but we engineers have to find solutions that are both effective and economical.

WHEATHER QSHAKE HATE TO BELIEVE THE ARGUMENT THAT WE ENGINEERS HAVE TO FIND THE SOLUTION THAT ARE BOTH EFFECTIVE AND ECONOMICAL.BUT I BELEIVE THA MOST COST EFFECTIVE SOLUTION CAN BE EVOLVED SO THAT OUR CLIENT CAN HAVE TODAY'S TECHNOLOGY RESULTING COST EFFECTIVE ENGINEERING SOLUTION.

Aldorankin...I'm not sure which "method" you are referencing, but there is plenty of literature on the interaction you have described. Is there a simple checklist and go-by for the exact condition you have described? I doubt it, but given the pieces and parts there is a method by which you can resolve the answer with support from many established and authoritative writings, including some of the tips in this thread (go back to Qshake's tip and diagram). It is called "Engineering"!
