v3.04.115 SSLV115 - Concrete element prestressed under compression and gravity

Summary:

This test allows a simple verification of gravity calculations for concrete elements with prestress cables, in the mechanics of linear static structures.

The concrete element is solid, and the prestressing cable elements are elements BARRE or elements CABLE_GAINE with an adherent law.

The models \(A\), \(B\) and \(C\) make it possible to test the application of gravity on elements BARREou of elements CABLE_GAINE, for two directions of gravity.

The values tested are the results of the reactions on the supports, equal to the total weight of the modeling.

This test case also makes it possible to validate the CALC_PRECONT command for various types of \(\mathrm{3D}\) elements (parallelepipeds, pyramids and tetrahedra). To do this, the calculated stress values are checked.
