I am evaluating an existing floor for the weight of a nuclear medicine scanner. The structure is concrete joists and slab with concrete beams. One bar placement and bending diagram is provided that includes both joist and beam details. The typical top bars, bottom bars, and bent bars are shown. The joist schedule refers to bottom straight bars, bent bars, and additional top bars. This all makes sense with the diagram. But the beam schedule shows bottom long, bottom short, and top bars. I cannot figure out the difference between the bottom long and bottom short bars and the details do not refer to them this way. Does this refer to the straight and bent bars? Seems weird if that is the case because the joist schedule on the same page refers to bent and straight bars by those names, matching the diagram. Is there some other interpretation of this? Can anyone help with this? I have uploaded the details as well as excerpts of the plan and schedules.
