I am searching the procedure for detailing of concentric slab having inner radius as 6m and outer radius as 9m. The slab rests on curved beam which in turns rests on main rectangular beam.
In India the codal provision for detailing of concrete slab was Is 456:2000,and Is 13920:2006 for Limit State of Design.
But you are concentrating on circular slab I recommend rather than going for limit state design you can prefer working state design.
These type of slabs are very common in circular overhead tanks. IS 11089 provides guidelines about calculation of moments in radial and transverse direction and reinforcement has to be provided in the form of radial and circumferential directions with minimum reinforcement as per foundation requirement.
If you have no problem regarding the calculation of reinforcements and just you need to know how to do the detailing, you can just follow the common practice in your own market provided that the overlap and developed length, etc are all according the standards used in the design process. The main idea from detailing is to let the site engineer put the reinforcement as you wish.
