In this video tutorial series, we’ll look at the calculation and design of a cracked reinforced concrete slab, i.e. deformation in State II.
In principle, there are two approaches in :
1. We perform a linear crack analysis by reducing the stiffness of the slab.
While this is very simplified, it is often sufficient and, above all, convenient because the superposition principle applies.
2. We perform a detailed nonlinear crack analysis.
Both methods allow to determine the deformation of concrete structures in a cracked state as well as further results.
We’ll look at both methods in this video series, starting with the basics: a linear uncracked analysis.
