QUESTION: Are the Live Load reactions in the Conspan output multiplied with Distribution Factor and Impact factor ?

ANSWER:

Generally the Live load reaction shown in the conspan output is for  the whole support and whatever LL reaction the user gets for the whole support is per lane and is not  multiplied with DF and IM factor. To get the unfactored LL reaction for each bearing location just multiply it by appropriate Number of lanes , DFs based on exterior and interior beams .

Its left to the user to decide whether he/she wants to multiply with the DF and IM factor . Some cases the user wants the reaction with DF only and in some cases both IM and DF.
