composite slab shear capacity
composite slab shear capacity
(OP)
Does anyone have experience in design for both vertical and longitudinal shear for composite slabs?
By composite slabs I mean a precast concrete plank, acting as self supporting formwork, with a insitu concrete topping slab.
Commercially manufactured composite slabs usually don't have shear connectors, relying on the concrete bond only. How would this affect vertical shear capacity?

RE: composite slab shear capacity
As a result, the horizontal shear required for composite action is usually small enough that the coefficient of friction from ACI will suffice. I believe it is 1.0 for for concrete placed against hardened concrete that is intentionally roughened - that is why they rake the top, to get a good bond between the topping and the plank.
