Hello there; Delete the last two modal analysis cases that you added from the structure tree. Update the mod count to 200. There is no joint in your beams located in the region of the central vertical braces in the system. Define hinges to these beams or single slip plate joint etc. enter a slip combination. You did not place a basement screen sign on the curtains, do so. Check the correctness of the parameters you entered for DD-2 and DD-3 from the analysis settings wizard. We have edited the number of modes and freedoms this time, check the analysis settings wizard. There doesn't seem to be anything that can be done apart from these, you need to increase the cross section. Good work.
