Hello everyone, I am modeling a 3 storey concrete building with moment frames in both directions and rigid diaphragms. There are 3 expansion joints on each floor. How do I model the diaphragms such that the expansion joint is accounted for? (i.e. capable to transfer vertical load but unable to transfer horizontal forces). Please, let me know if there's a specific command or if there's a way to trick the program. Thank you.
