1. Reference problem#

1.1. Geometry#

We consider a model structure in the form of a horizontal square slab having \(1.3m\) thickness and \(10m\) sides, supported in four corners by springs. The slab mesh contains three subdomains meshed in triangles and quadrangles with three interfaces: a compliant interface (coincident nodes) between sub-domains \(\mathit{DALQ1}\) and \(\mathit{DALQ2}\) and two non-compliant interfaces between sub-domains \(\mathit{DALT3}\) and \(\mathit{DALQ1}\) and \(\mathit{DALQ2}\).

1.2. Material properties#

The slab is made of reinforced concrete modelled using the global law GLRC_DAMAGE.

1.3. Boundary conditions and loads#

The slab is supported by four springs whose stiffness is specified. The slab is loaded by a uniform surface pressure whose appearance in time is determined by a function.

1.4. Initial conditions#
