FAQs: How is the MBE lane-type legal load model defined?

Question

How is the MBE lane-type legal load model defined?

Answer

The MBE lane-type legal load model contains a truck and a lane load (MBE Appendix D6A). The model applies for the following two cases:
1.     Spans greater than 200 feet for all load effects. The live load type for this case is truck + lane.
2.     Negative moment and interior reactions for all span lengths. The live load type for this case is truck pair + lane. The legal pair check box in the Analysis Setting/Vehicle Properties window must be checked for this case.
