VERSION 21 IN CONCRETE – OVERVIEW

7 7
RCS – FIRE RESISTANCE FOR SLENDER COLUMNS
20.1 21
• Extended checks for the fire resistance according to EN 1992-1-2 Annex C
• Suitable for slender columns with 30 < λfi ≤ 80

8 8
RCS – STIFFNESSES
20.1 21

9
Version 20.1 and older
• Increment of the stress and strain in rebar caused by V+T was calculated with assumption of linear-
elastic behavior of the rebar
9
Version 21
• Real axial stiffness and tensile strength of each rebar
• Increment of the stress and strain in rebar from V+T is calculated with consideration of non-linear
stress-strain diagrams of reinforcement.
• Limited interaction check improved: N-M-M + T (acc. EN 6.2.3 (7) without shear)
RCS – INTERACTION
For shear and longitudinal reinforcement
