RE: auger cast piles

[Subject Prev][Subject Next][Thread Prev][Thread Next]
How do you get the requirement for LRFD out of 1809.3.5?

Thanks,

I think it depends on the Seismic Design Category. If your building is
categorized A or B, I guess you can use ASD (1801.2). However, for C, D, E
and
F, you need to design based on LRFD (1809.3.5).
I hope it help you.
