Does RCDC design the irregular slab like L, T shapes and slab having more than four edges?

Yes. Rectangular and odd shaped slabs can be designed in RCDC. RCDC designs the two way and irregular slab based on yield line theory. For odd shaped slab RCDC considers the largest span as shorter direction for design. For Aspect ratio (L/B) RCDC considers the outer-most dimensions of the irregular slab. As per the aspect ratio of irregular slab it identifies whether the slab is one way or two way. For design using ACI, the two way and irregular slab are based on direct design method.
