QUESTION: How does CONBOX calculate the live load distribution factor when the range of applicability of Table is not satisfied (for example when number of cells is less than 3)?


For box girder with less than 3 cells . The program designs the box girder by 2 cell methodology and 1 cell methodology.  These methodology is basically based on Caltrans Amendments to AASHTO LRFD bridge design specifications – 4-36A and 4-41A.
