Introduction
============

As part of the study of the performance of civil engineering buildings, numerical simulations aim to better understand their non-linear behavior. This document presents the tools available in *Code_Aster* in order to model slender reinforced concrete structures (Q4GG shell modeling) with prestress cables and to perform a rapid dynamic analysis using the *Europlexus* software. For more technical details on the data processing of an impact calculation with law GLRC_DAMAGE, you can consult the reference [:ref:`8 <8>`].

The purpose of this document is to provide the user with advice for setting up study data with prestress cables that may be adherent, slippery or rubbing.
