    Load Percentage

    Sorry, didn't recheck the forum. The original design had a single rod with each floor (and therefore each nut) supporting the weight of 1 floor. By offsetting the rod connecting the lower floor, the upper floor now supports both the lower and upper floor weight. So the nut in question (and the floorbeam) now has to support both floors, and was not resized for the additional forces.

    Looks like a case study of the Hyatt Regency Collapse. Load on the nut doubles with the offset.
