RE: Seismic Equation Misprint?

Yes, the errata notes that the formula should read:


6. (1.0 + 0.105 SDS) D + H + F + 0.525 ρ QE + 0.75 L + 0.75 (Lr or S or R)

check out page E-4 - it's part of the 9.15.06 errata

I am looking at Section of ASCE 7-05 “Basic Combinations for Allowable Stress Design”  Equation #6.  Should the second term in the DL portion of the equation be .105 Sds or should it be .10 Sds?  I looked at the latest Errata and it wasn’t mentioned.
