i have watched lots of video about slab design, but the way u taught me i totally loved it. Thank u so much sir. Just i have one doubt about the effective depth(d), i.e why dont u consider dx and dy in the time of calculating astx and asty as u r providing reinforcement in both the direction(x,y)?

My duobt is if there is one way slab next to two way slab and the longer direction of both the slab is in same direction so longer side of two slab is considered as continuous or not?? Main point is we don't provide bentup bar in one way longer direction so will I continue the bar of longer direction of two slab into the one way slab as case define above if yes we need to provide distribution for bentup bar which was continuoued into the slab??

If they have beams under it. It won't be considered as cantilever slab. Best example of a cantilever slab is a chajja over window which is free standing supported at the beam. Hope you understood? thanks for watching keep supporting.

Now while providing Ast top he says 50% is coming from Ast bottom ... Thus actual Ast top to b provided is = (Ast top reqd. - 50% Ast bottom) Can this be applied for 2 way slabs too?
