effective width for a slab design - wall on balcony

[n3jc]

Hi,

Im dealing with a wall on a slab (balcony) - see attached picture.
What do you guys recommend for an effective width(beff) when designing a slab?

There probably is some definitive guidance somewhere, but since you asked what we would do, I would use about a metre.

n3jc,

Attached is the recommendations from BS 8110 (old UK concrete code, now Eurocodes) on how to work out the effective width.

Tnx for answer, but Im not dealing with concentrated load.

I dont think I can consider alfa as 45 degrees?

Is it a concrete or a masonry wall?

Recommendation von patswfc looks reasonable, I would use it, or go with some FEM program.

Tnx for answer, but Im not dealing with concentrated load.
Well change your line load in x point loads (your program does it too...

tnx for reply. Its a masonry wall.

AASHTO used to have an effective width for cantilever slabs with wheel loads: E=3.75+0.8X, where X is the perpendicular distance from the supporting element to the load. You could treat your wall as a series of concentrated loads and add the effects. You could find out how that formula was derived, or, would drop the 3.75 from the formula and just use E=0.8X.
