Purpose: Used to limit the user-defined truck to one lane when determining the possible types of loading in combinations of multiple lanes in Girder System Projects using direct lane loading. (Not applicable to Line Girder Projects.)
--> Given in girder system input
The truck defined by AXLEP and AXLESP is used only on the single lane which is closest to the girder for which live load effects are being determined if both a standard truck and a user-defined truck are used. The standard truck is used for all other lanes. Governing effects from loading on the single closest lane are determined by a comparison of effects from the user-defined truck with effects from the standard truck loading on the same lane.
