Concrete Piles w/ an R = 1.0!!

[Subject Prev][Subject Next][Thread Prev][Thread Next]
To All,

For designing an underpinning concrete pile, (caisson), foundation of an existing structure where the piles are a cantilevered element, (no grade beams at the top), ASCE Table 12.2-1 Item "G" requires an R of 1.0 for seismic loads. Can anyone give me some input on justification to use a higher R value, or am I stuck with the R of 1.0?

Thanks in advance,

Larry Hauer S.E.
