Assalam o alaikum,
I am to model a basement in ETABS. Basement has 4 side walls and a slab at top. If I model slab as it as at top of walls, it behaves as partially fix support and produces moment at connections between slab and walls. But i want to release this moment.I want my slab to behave as Simply Supported where it connects wall and as monolithic where slab connects with beam and also I want my walls acting as Propped Cantilevers instead of both ends fixed. Also suggest me how to provide same connection in real by detailing of reinforcement.
Jazak Allah.
Thanks.
