Where uniform roof live loads are reduced to less than 20 psf 0 96 kn m 2 in accordance with section 1607 12 2 1 and are applied to the design of structural members arranged so as to create continuity the reduced roof live load shall be applied to adjacent spans or to alternate spans whichever produces the most unfavorable load effect. 1607 12 4 awnings and canopies.

These loads are not considered to be per manent because of their inherent degree of variability with respect to time see the definition of loads in ibc 202.
