Hello,
I am modeling a building that has a concrete pan joist system. I model the columns, support beams, pan joists (using the pan joist tool), and slab. I wanted to check my work so i did no apply any external loading, but entered the concrete design tab to check the self weight reactions. When I check the max moment on a joist, I am getting a number that is 2x the expected moment from self weight. I then deselected the slab self weight and got a number that was closer to the expected results, but still a couple k-ft smaller.
I have never used RAM to model concrete before, is there a trick I am missing?
Thanks,
ANdrew
