If we have already created a LEAP Steel model and now need to load rate the superstructure, is there a need to use LARS for the rating? The owner requires several Legal Load trucks and a permit truck.
Is there a way to open a LEAP Steel model in LARS?
LARS checks the compression flange and tension for top and bottom for each checkpoint. This is performed because any checkpoint along a beam may be the location at which contraflexure occurs. When the top flange is in compression and the bottom flange is in tension, top fiber +bend and bottom fiber +bend should be considered as a pair.
