chigozie,
thats a just a simple calc done by king12. i am not trying to side the super mod here but i when king12 posted a spreadsheet on cantilever slab, he does not expect comments on the load used in the sheet. he will definately titled his thread here as 'loads used for cantilever slab' if he wants that. and why do't you try to reason out whether he has done anything wrong in the section design? whether the lever arm was computed correctly etc?
and instead u try to dictate the loads he keyed in? and your replied kowheng with almost half a screen when he try to 'guide' you of your post.
from your posts here you must be an experienced engineer, why do you want to create a debate out of a simple cantilever slab calc.
you said should not overload the structure. for your arguement sake, why if the architect wanna a 4" thick marble floor at this cantilever slab? and what clause in BS that we need to go to 1:7 ratio for cantilever slab? the modification factors for tension and compression reinforcement, what are they for? they are always more than 1.0. imagine a window hood with virtually no imposed load, you still follow 1:7 ratio for it? you are instead misleading with your post. and can you design to IS? do you know what's in there?
i presume you will write another half page to reply and i advise you, go to the problem section, take on those heavy topics with others experienced engineer and leave alone our fellow king12. thank you.
