Pile lateral load rule of thumb

Hi,
I want to know if there are any rule of thumb that can be used to rough estimate lateral loads on piles or cross section dimensions of piles supporting/beneath a foundation of a tall building, based for example on the soil type and the axial load?
I want to determine size of piles without being forced to do a detailed or FInite element analysis.my purpose is preliminary design so in advanced stage of design of course the design will be done in details and using a finite element software.
I appreciate your replies.

Broms method is very simple to input in a spreadsheet, there are better methods but its a good a place to start as any

Is Broms's method for long piles applicable for pile in rock?

Have you reviewed Broms method?

The original poster should more clearly explain what the situation is. If the building is supported on these bearing piles, where is the lateral load coming from?

There is no correlation between the axial load and a lateral load on a pile, it depends on your structure.

You could have a pile with 100k axial + 1k lateral load.
You could have a pile with 1k axial + 100k lateral load.

There are several approximate methods of structural analysis that you could use to get a rough idea of the reactions for your building.

@EireChCh.I viewed Broms method in the link sent..it answers my question but not sure if applicable also for rock(only cohesive and cohesiveless soil are treated in the pdf)

Checkout section 9 of the FHWA Bored Pile manual (https://www.fhwa.dot.gov/engineering/geotech/nhi18...) you may find something useful there.
