How is this structure supported only at the edges?
This picture is a popular discussion in many social media pages.
The discussion is around the support of the the slab ''only at edgs''
I happened to see this when a student tagged me to the post and asked how is this supported. Thought of posting here for other students who may have a similar question.
If you look at this closely,you can see that,it is a normal structural system.You probably have 150 to 200mm overlap and that is good enough to run 2 numbers through bars top and bottom.Thats a beam!
I dont know the spans.However as long as the beam can have adequate depth appropriate to the span, this is possible.For aesthetics,the slab has the same depth as that of beam.
See the sketches below for more understanding.
