The attached example model, tests an example of design supports. The mid-span deflection of a 3m-wide span deflection is 11.1 mm which is bigger than the limit value of L/300 = 3000 /300 = 10 mm
There are two member sets meeting each other to the left of the mid-span with a hinge. I defined design supports at both ends, and applied SLS check to them. The check is not picking up the exceeding deflections.
Because of the hinge in the middle, there cannot be a continuous member set across the span. So then how to model this situation so that the steel designer detects to exceeding deflection in the floor?
