u2.03.08 Realization of a civil engineering study with prestress cables in rapid dynamics via the macro command CALC_EUROPLEXUS

Summary:

The purpose of this document is to provide advice for carrying out civil engineering studies in rapid dynamics with prestress cables and shell-modelled concrete (Q4GG element). The calculations in rapid dynamics are carried out with*Europlexus* via the macro command CALC_EUROPLEXUS. Prestressing cables can be of three types: adherent, slippery or rubbing.

We recall the three types of cable modeling available in Europlexus and illustrate their use on the example of a prestressed enclosure subjected to an impact. We will present the four steps for solving the problem: creating the mesh, putting data into Code_Aster, solving the numerical problem and post-processing.
