Because RAM Concept assumes that deep beams behave like slabs, RAM Concept will not consider that a step beam could bend about its longitudinal axis. RAM Concept ’s assumption that "linear sections remain linear" prohibits this type of bending and will cause RAM Concept to over-estimate the stiffness of the step-beam for moment transfer.

This over-estimation of the stiffness is generally not significant and is normally ignored. However, it is up to the engineer to assure that step-beam has the capacity and detailing to transfer the analyzed moment.
