>concrete design? In UBC chapter 19, all the ACI load combinations/load
>are given EXCEPT for earthquake. Section 1909.2.3 states that the load
>combinations/load factors of Section 1612.2.1 are to be used. Does this
>ONLY the load combinations with "E" or does this mean to use all the
>1612.2.1 load combinations in lieu of the ACI combinations?
