u2.03.11 Steel Concrete Structures.

Summary:

The objective of this document is to provide recommendations for modeling « Steel Concrete Structures ». This document deals with the modeling of walls, floors and the junctions between the various structural elements. Different approaches are possible and the aim of this document is not to replace the engineer’s analysis but to allow him to choose modeling options while alerting him to certain models that may lead to « unrealistic » results.

This document also discusses laws of behavior as well as post-treatment.
