I'm analyzing a one way concrete slab and beam structure with moment frames in both directions, and I'm getting significantly larger design moments in RAM Concrete Column than I am calculating from the loads output from RAM frame. I have RAM Concrete set to use gravity forces from RAM Frame. This is not an issue when I use RAM Concrete analysis forces.
P-Delta is turned on in RAM Frame, slenderness is not considered in RAM Concrete.
Below is an example of the RAM Concrete Column design report, followed by the RAM Frame forces. RAM Concrete says the Major Moment is 743.13'k, while the results from RAM Frame give 573.36'k for the same load combination. What would this difference be caused by?
