Hollow Spun Piles
Hollow Spun Piles
(OP)
Anyone have experience with hollow spun piles? I was wondering about the advantages and disadvantages of these piles. Also, any information on the standards and specifications used for their design would be helpful.

I'm not sure if the same pile would be economical for all solutions today pending the applications. As an example, if you google the CBBT you'll see reptition upon repetition of concrete bents and that makes a good case for economy of size/numbers. But if you had a relatively small number, I would think they are very expensive.

Available pile dimensions are as follows:
Diameter(mm): 350 400 450 500 600
Thickness(mm): 70 75 80 90 100
Length of each section: 6 - 16 m
Given properties are: area of steel, area of concrete, sect modulus, effective prestress, cracking moment and ult moment. Spun piles have been used for multy storey buildings, industrial buildings, bridges.

The pre-stressed piling can: transition to a pre-stressed, cast-in-place, hybrid or timber floor system, carry a higher moment with the same skin friction as timber, and require less foundation (at ground level) for the structural slab, sometimes no slab at all. Check out www.gateprecast.com & www.flexicoreoftexas.com more info on Pre-Cast/Stressed Concrete products
The hollow fiberglass composite piles allow you to design a very tall structure with Cast-in-place column/piles by increasing the monolithic height vs break-out point where most forms would fail, we have never used the HFCP's as a hollow unit - but I am told that in a bulk heading or pier application they are wonderful.
