Hello Sean , at time 8.05 :
As you said , this corner effect will be applicable only if we have simply supported systems right? (not in free edge or fixed edge),
In other words, if we have a cantilever terrace area lets say, fixed with 2 columns behind 2 other corners of this plate is hanging as stated in cantilever state, then we would not have this corner effect , right ? Because there are 2 free corners now (1 free edge for cantilever) right ?
Or maybe this corner effect is still happening in cantilever case ,but tension at top and compression at bottom (so kinda reverse direction of corner effect) , so are we still observing this effect in a reverse mode or maybe i am just misinterpreting (definititely could be just thinking out loud )
Thanks a lot,
Burak
@m.burakcakir33 - the corner uplift will only occur when we don’t have any corner anchorage. So, if the edge is fixed, no uplift will occur as the slab is restrained. Similarly, if we have a free edge, the slab is free to deflect, and so naturally we won’t observe any corner uplift. So, in your case of a cantilever terrace, corner uplift due to torsional moments is not a concern.
