One Way/Two Way Slab Systems
One Way/Two Way Slab Systems
(OP)
Hi guys,
Have this scenario whereby two one way slabs are intersecting. The overlapping (rectangular) slab is not supported on two sides like the one way slabs are by walls below. There is a wall running along beneath one edge of it and the other two opposite corners can be deemed as being fixed; these are the support conditions.
Therefore, it is more of a two way system.
What's the best way to design this (as quickly as possible)... I'm using CSA A23.3 also.

RE: One Way/Two Way Slab Systems
The difference with a 2way slab is that it is happening in 2 directions at once, so you end up with a variatioon in the moment in the stronger column strips between -ve and +ve moment areas. If all of your supports are walls in this case, then you need a strong band to carry the slab load to the supports. This band will carry itself plus the extra load dropped onto it.
