4.1. Behavioral law and material parameters

The law of behavior tested is” MAZARS “, it is documented in doc [R7.01.08]. This fragile elastic law makes it possible to account for the softening of concrete and distinguishes between tensile and compressive damage.

The elastic parameters are as follows: \(E(T)\), \(\nu (T)\), and \(\alpha (T)\)

The elasto-plastic parameters are: \({\varepsilon }_{0}(T)\), \({A}_{C}(T)\), \({A}_{T}(T)\),,,, \({B}_{C}(T)\), \({B}_{T}(T)\) and \(k\)

Values of the parameters used:

Settings	\(T\mathrm{=}0°C\)	\(T=500°C\)
\(E(T)\)	\(32000.\mathit{MPa}\)	\(16000.\mathit{MPa}\)
\(\nu (T)\)	\(0.2\)	\(0.18\)
\(\alpha (T)\)	\(1.2E\mathrm{-}5{K}^{\mathrm{-}1}\)	\(2.0E5{K}^{\mathrm{-}1}\)
\({\varepsilon }_{0}(T)\)	\(0.0001\)	\(0.00005\)
\({A}_{C}(T)\)	\(1.4\)	\(1.0\)
\({A}_{T}(T)\)	\(1.0\)	\(0.8\)
\({B}_{C}(T)\)	\(2000.\)	\(1000.\)
\({B}_{T}(T)\)	\(10000.\)	\(20000.\)
\(k\)	\(0.7\)	\(0.7\)
