Curved Concrete Balcony Slab with Edge Beam
Curved Concrete Balcony Slab with Edge Beam
(OP)
Hi,
I am looking at a design of a rectangular balcony slab with 1 outer curved edge, the slab is well supported on the ends (built in) and also has a small amount of support at the ends of the curve, I would estimate the curve has a max. offset of 550mm and has an edge beam (down stand). As the edge beam will be cast monolithically with the slab am I right in assuming if the reinforcement is detailed correctly the beam will not develop torsion as the slab will provide restraint. therefore the beam can be designed as simply supported with the span = curved length but detailed to tie adequately into the slab.

I am designing by hand but have the design done. Also I would be interested in anyones thoughts on this situation if the beam is an up stand. (up stand maybe 215 wide X 300mm Ht.)

Ishvaags comment was based on the assumption that it is a steel beam but it is apparent that the beam is concrete.
You should always provide closed ties to these things mainly for serviceability.

I do agree that the curved beam will provide edge stiffening.
