Eurocode 2 ULS design of circular (or tubular) reinforced concrete cross-section for bending and axial force

Description:
ULS design of circular or tubular reinforced concrete cross-section for bending and axial force (the maximum moment resistance MRd is calculated for the given axial force and reinforcement layout, or the complete M-N interaction diagram is determined)
According to:
EN 1992-1-1:2004+AC2:2010 Section 6.1
Supported National Annexes:

MPa
e.g. 30 MPa for concrete class C30/37. For a list of concrete classes see Table of Concrete Design Properties
MPa
The elastic-perfectly plastic model (no hardening) is permitted in EN1992-1-1 §3.2.7(2) with unlimited strain. A strain limit of 75‰ is consider in this calculation for numerical reasons. Alternatively stress-strain laws with hardening and limited strains may be considered according to the ductility classes A, B or C specified in EN1992-1-1 Annex C.
