The equation for shear strength of a RC section without shear reinforcement in the various codes takes into account the ratio of longitudinal reinforcement "in tension", which acts as a crack width limiting factor or through dowel action to aid in shear strength.
Example from EN1992-1-1:

Suppose we have a slab with an offset that at the same time acts as a supporting beam (happens a lot in projects where there is an underground garage for example). In the static analysis the slab is assumed to be continuous. The beam acts as a support therefore the moments in the slab will be...
Assume a RC continuous two-span slab with pinned supports on all sides and a T-Beam acting as mid-support. The beam is supported by columns on each end (assume high flexural stiffness of columns).
Let's take two scenarios:
1) Slab span lengths and loading are equal, there is a force F acting...
In the case of a base slab with a thickness of 60cm supported on piles with diameter of 44cm-60cm, we have a situation where the punching shear perimeters overlap (using EC2 parameters for Germany). The slab is loaded by walls scattered around. How could we check for punching shear of the piles...
