u2.03.06 Carrying out a building structure study with prestressed cables

Summary:

The purpose of this document is to provide advice for carrying out reinforced concrete studies with prestressed cables using dedicated functionalities (DEFI_CABLE_BP/CALC_PRECONT). It provides information on mesh precautions, on the methods of applying prestress and on the possibilities of phasing.
