ANSWER:
Optional Live Load Deflection (LRFD Design Code Only)
According to the LRFD design code, if the user invokes the optional live load deflection criteria specified in LRFD Article 3.6.1.3.2, the deflection should be taken as the larger of (a) the resulting deflection from the design truck alone, or (b) the resulting deflection from 25% of the design truck taken together with the design lane load. If you select the “Include LL Deflection” option, the above two conditions are checked and the deflection under the governing load is printed in the camber and deflections section of the printout.
