Seismic Tank Design - ACI 350.3 and ASCE 7-10 15.7.7.3

[briancpotter]

I'm currently designing some concrete tanks for a wastewater treatment plant. Previously to calculate the seismic loads, I used the method from ACI 350.3, with the substitutions from ASCE 7-05 chapter 15, section 15.7.7.3.

I'm currently looking at the same chapter and section in ASCE 7-10, and it's been changed in a way that's confusing to me. It's pointing to 9.4.2 and 9.4.3 in ACI 350.3, but as far as I can tell these sections don't exist.

Anyone with water tank design experience care to shed some light?

Both of 9.4.2 and 9.4.3 are available in 2006 edition of ACI 350.3, referred on page 233 of ASCE 7-10. Are you looking in some other edition?

I figured it out - I'm referencing the ACI Manual of Concrete Practice 2006 edition, which for inexplicable reasons references ACI 350-01, not ACI 350-06.

Thanks.
