Hi Jack, two-way spanning slabs can have linear supports along their edges (for example, beams) or they can be supported solely by columns (in which case they are generally called flat slabs). In either case, for a manual design (i.e., handwritten calculations), I would follow the design advice provided in the IStructE Manual for the Design of Concrete Building Structures to Eurocode 2. The applied load is carried equally by the slab spanning from one side to the other and also from one end to the other for a linear two-way slab square shaped on plan, with length and breadth the same. As a result, the reinforcement in both directions will be equal. When a linear two-way slab has a length that differs from its breadth, the shorter span carries more of the load and the longer span carries less. The above-mentioned manual provides coefficients for bending moments and shear forces in these situations. I hope this was helpful.
any justification for your assumption of shear stress? in actual situasion we have to determine the shear stress, so by referring your example tutorial, kindly advise me how to determine, what kind of info we need?
I wish I had you as a lecturer while completing my degree. We struggled unnecessarily with structures..
U are simply the greatest!!! Keep doing what you do. I would love to see your take on a moments connection of a UB to UC to Eurocode.
A very clear presentation. Well done!! Keep making these videos, they are excellent!
Your vids are invaluable Cheers
Thank you for making these videos, much appreciated!
Wow awesome tutorial keep them coming for concrete design :)
Thank you for the videos, very helpful
Excellent video, thank you so much. Please cand you make a video of how to covert point load to area load.Thank you
Thanks for the videos... much appreciated... would you mind making a similar one for column sizing
Hi SECalcs, how would you design a two-way supporting slab ?

Excellent Thank you very much.
How much re-enforcement (diameter of bars and number of bars) do you have to put in the concrete beam?
How can we assume the shear stress 1.2 .Is any parameters are there's tress?

Where did you get the values of the dead and impose load?
These were assumed for the purpose of this example.
