Ing please how to you apply floor load to cantilever slab. It does not work. Secondly I'm am wondering why you didn't release moment at certain points.
Great question Ahmed. You do not apply floor loads on cantilever slabs. The essence of floor loads is to adequately transfer the distributed loads from two way spanning slab panels to the boundary supported beams in line with the yield line failure mechanism of the slabs (Please refer to Table 2.52 of Reynolds's Reinforced Concrete Designer's Handbook - 11th Edition. This contains various yield line configuration for supported 2-way slabs). So because a cantilever slab is typically a one way panel where the aspect ratio is ≥ 2, the distributed load (either dead or imposed) 'q' from the cantilever slab of length 'l' on the supporting beam is ql. Floor loading do not apply to cantilever slabs. As regards moment releases 'Mz' on certain beams which are theoretically assumed to transfer only shear forces (i.e if the members are adequately detailed (and constructed)to prevent effective moment restraints), this was intentionally left out for analysis purposes as the releases are specified in advanced concrete designer module in STAAD prior to the design against shear and flexure.
