Composite Secant Files
Composite Secant Files
(OP)
I have a 3'10" diamater secant pile with a W27x84 soldier pile spaced everyother pile (6.25'). The compressive strength of the concrete is 4 ksi.How can I determine the composite bending capacity of the the secant pile? I am currently exceeding the bending moment of the wide flange and need to start taking into account the strenght of the concrete.





RE: Composite Secant Files
In my experience the contractor always prefers a heavier beam with no shear connectors to a lighter beam with the connectors. You can easily fit a larger beam in that large a shaft.
If you need to use that size beam, the AISC manual goes through the steps of composite beam design.
