3. Modeling A

3.1. Behavioral law and material parameters

The law of behavior tested is” BETON_REGLE_PR “, it is documented in the documentation [U4.43.01]. This law of concrete behavior is called a « rectangular parabola ».

The elastic parameters are as follows:

\(E(T)\), \(\nu (T)\), and \(\alpha (T)\)

The elasto-plastic parameters are as follows:

\({E}_{T}\), \({\sigma }_{y}^{t}\), \({\sigma }_{y}^{c}\), \({\varepsilon }_{C}\), and \(n\)

Values of the parameters used

Settings	\(T=20°C\)	\(T=500°C\)
\(E(T)\)	\(30000.\mathit{MPa}\)	\(10000.\mathit{MPa}\)
\(\nu (T)\)	\(0.\)	\(0.\)
\(\alpha (T)\)	\(0.5\mathrm{\times }{10}^{\mathrm{-}5}{K}^{\mathrm{-}1}\)	\(0.8\mathrm{\times }{10}^{\mathrm{-}5}{K}^{\mathrm{-}1}\)
\({E}_{T}\)	\(\mathrm{-}10000.\mathit{MPa}\)	\(\mathrm{-}10000.\mathit{MPa}\)
\({\sigma }_{y}^{t}\)	\(3.\mathit{MPa}\)	\(3.\mathit{MPa}\)
\({\sigma }_{c}^{t}\)	\(30.\mathit{MPa}\)	\(30.\mathit{MPa}\)
\({\varepsilon }_{C}\)	\(1.\mathrm{\times }{10}^{\mathrm{-}3}\)	\(1.\mathrm{\times }{10}^{\mathrm{-}3}\)
\(n\)	\(2.\)	\(2.\)
