Dear Engineers, I have modelled separately two different floors on ETABS and in between is a secondary beam connected to primary beams at the ends. When I pin the secondary beams and do analysis and design,the floors seem to ignore the secondary beams by acting as a single span resulting into longer span with increased deflection and higher reinforcements required.I have attached a file showing this. When I make the joints of the secondary beams fixed,the floors now act as expected;as two separate spans thus giving correct deflection and reinforcement results. I want to keep the pinned secondary beams but again I want the floors to behave normally(maintain separate spans).How do I fix this issue? Kind Regards, Kel

While providing release in secondary beam in etabs, we do not provide on joint directly and on intersections having other secondary beam, we only provide on the end where it is joint with primary beam only, why?
