IBC 2009 Table 1607.6 - Application of Uniform and Concentrated Loads
IBC 2009 Table 1607.6 - Application of Uniform and Concentrated Loads
(OP)
Do the uniform and concentrated loads shown in Table 1607.6 need to be applied at the same time? The main text of the code seems pretty clear that they do; however, the commentary specifically states that these loads are to be applied as separate load cases and not at the same time.

The code is fairly clear about combining these loads. See 2009 IBC §1607.6.1:
"Single spans shall be designed for the uniform load in Table 1607.6 and one simultaneous concentrated load positioned to produce the maximum effect. Multiple spans shall be designed for the uniform load in Table 1607.6 on the spans and two simultaneous concentrated loads in two spans positioned to produce the maximum negative moment effect. Multiple span design loads, for other effects, shall be the same as for single spans."

This is what is causing me the confusion because it seems to directly contradict the what is stated in the code.

I agree that the distributed and uniform loads need to be combined. Sometimes the person writing the commentary gets it wrong. I've seen it happen before. The commentary is just an opinion, it's not part of the code. The commentary may have been updated, which would explain the on-line version being different from the version waytsh has.
