This is better information than most universities sell

wonderful, thanks

Throughout this entire video, you confused the 10% and 40%. 10% is referencing the depth of the beam, from the surface of the ceiling. The 40% reference is the space BETWEEN beams, not depth of the beam.

Dear sir ,, I have a case in my hospital project,, there are main corridor, in left and right of corridor we have rooms divided along but the front face of rooms are open to main corridor but have depth beam in front face greater than 0.1H of ceiling , do we consider rooms are separated from main corridor? And what if we don’t have depth beam ?
