TWO CLOSEST LANES

 

Purpose:  Used to set the number of lane combinations to consider for live load envelopes in Girder System Projects using direct lane loading.  (Not applicable to Line Girder Projects.)

 

-->    Given in girder system input

 

Only the two closest lanes to each girder are loaded to determine live load effects for ASD or LFD.  For LRFD loading the governing case of one or two lanes applies.  (Also see ALL LANES , which is the default.)
