Rebar Layout
Rebar Layout
(OP)
For pile caps with three piles (3 piles forming a triangle, column on center), designed using strut-tie method or truss method, aren't the rebars supposedly parallel to the 3 tension chords of the strut-tie/truss model? which in this case would form a triangular shape on plan.
However, on most drawings that I have seen, the rebars arent laid out in this manner. The rebars are often laid parallel to the plan orthogonal axis (Horizontal and vertical axis at right angles). I know it is more practical, but isn't this an incorrect way of laying out the rebars for the tension chord? I dont think that the 2 tension chords, oriented at 60 deg on plan (the third tension chord being parallel with the x-axis) could be converted to an equivalent x & y tension chord.
anyone care to help me on this

In these situations, headed dowels in the piles are a good way to go.

What do you mean by "headed dowels in the piles"? What is their purpose?

Headed bars are covered in ACI and have helped many an Engineer and Detailer to achieve sobriety.

I'm pretty sure I've seen strut and tie done, though, when you have a grid or rebar that's not necessarily in the same direction as the load. It certainly conceptually seems like it should work.
