Pile design
Pile design
(OP)
I have been asked to design a residential home on elevated piles. The project is located in Mass, along the coastline. My intent is to design the piles using Lpile, however, I have a question regarding the lateral loading. Can anyone point me to a reference that provides the proper loading for waves/flooding?
Also, would using a program such as Lpile for this type of project be the typical method of design, or is there another method available?
Thanks,

RE: Pile design
I would think that LPILE would work very well for the lateral load response analysis. You will still need to check the geotechnical capacity of the pile under vertical compression and uplift loads separate from the LPILE analysis.
Don't forget to include wind loads (transferred from the structure) along with wave loads (on the pilings) in your load cases.

There is a fema document on coastal buildings that should also be followed for this.

I believe the US Navy has a TM, or whatever they call it, on wave loadings - I think I have a copy, but will have to look for it in my archives. I have used it in the past for loadings on floating pleasure dock systems.

LPILE is used for the geotechnical analysis of single piles under lateral loads and/or moments. Axial loads may be input to provide a first-order p-delta correction and to accurately model the state of stress within the pile section. LPILE provides an improved user interface and more cases over its public domain ancestor, COM624P.
Other less complex methods or software should be used in conjunction with LPILE to analyze the structural moment, shear and axial capacity and geotechnical axial capacity of single piles.
TonyES is correct in that GROUP will perform analyses for groups of piles, and likely uses the functionality of LPILE and SPILE (axial capacity) code (all 3 products have the same developer) for use in developing initial single pile results that feed into the multiple pile results.
