Determining Pile Capacity 1

[fzlo]

Hello,

Could anyone possible suggest a resource to help determine the pile capacity of an end bearing pile based of the allowable load? The allowable load is 800 psf and was unsure how I would be able to calculated the allowable pile capacity. The drawings that I received did not indicate this value as well.

Of course, the answer is dependent on many factors, not the least of which are:
Is this a single pile application? Or is this multiple pile arrangement?
Is this current question based on older drawings, when Allowable Stress Design (ASD) was prevalent in the industry? Or more recent where LRFD may factor into this?
Are there records indicating that the pile was actually driven to refusal, driven length matches up with rock depth.

If this is an old structure that you're looking for a preliminary design capacity (and based on pile achieving end bearing) then you can use the formula, (0.25*fy)*cross-sectional Area of pile.

If this is a multi-discipline project, given you are an electrical, I would not hesitate to reach out to the project geotechnical and structural to get their input.

Tomlinson, pile design and construction has everything you need.

But probably too mcuh info if you dont have the experience to understand the limitations.
