Hello,
I have been working in a RAM SS building model for some time and it has been running without any problems. Yesterday, I shifted a grid that has braced frames on it. After that shift, RAM has been omitting my lateral load cases in the "x" direction in load combinations, when considering notional loads in "all combinations in direction of lateral load". I can only get these load cases to run in combinations when not considering notional loads. I do not have any tension-only members in my model. I've tried deleting, re-entering the braces and columns many different ways, but have not been successful. Please help.
This appears to be a very unique case. The load combo generator does consider each of the seismic loads along with the notional load of the same direction normally, but in this file it stopped working. The work-around is to limit the notional loads to the gravity load combinations only, or to use custom combinations.
