Connections and flat plate

[gloomr]

Hi, I'm involved with design for the first time and hopefully not asking some really obvious questions. If my RCC building is not a moment frame system, what does the joint between a flat plate and column, flat plate and non load bearing wall look like? Does the slab simply rest on top without dowels?
Additionally, for the reinforcement on the edge strips that is not the interior strip, is the reinforcement mirrored from the interior strip reinforcement?
Thank you!

Your questions are basic to concrete design, yet are quite complex, and require training under a good mentor. You can't expect to learn the basics of flat plate concrete design by asking questions on the internet. Having said that, the first issue to resolve with a flat plate is punching shear, both at interior and exterior columns. At exterior columns, you must consider the eccentricity of loading which means the slab shear stress is quite variable across the section. This is often accounted for by using spandrel beams. As for non load bearing walls, they should be braced by the slab, but the slab should not bear on these walls, otherwise they would be load bearing.
