u2.03.10 Instructions for modeling junctions between reinforced concrete civil engineering structural elements

Summary:

The purpose of this document is to provide advice for carrying out studies of reinforced concrete structures comprising walls, slabs and foundations using dedicated functionalities (in particular kinematic links, a model of non-linear junction behavior). It gives information on the mesh methodology, on the implementation of kinematic links, on the parameterization of behavior models.

Nonlinear behavior, which makes it possible to model a flexural junction between a wall and a floor or a raft and affected on a discrete element (ball joints), of type DIS_TR on SEG2 meshes, with two nodes, with two nodes, accessible by the keyword JONC_ENDO_PLAS, accessible by the keyword, see §13 [R5.03.17].
