UBC Load Combinations

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Per the 1997 UBC, which load factors/load combinations are to be used for
concrete design?  In UBC chapter 19, all the ACI load combinations/load factors
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 mean
ONLY the load combinations with "E" or does this mean to use all the Section
1612.2.1 load combinations in lieu of the ACI combinations?
