Square plate:

Frames:

Length: \(l\mathrm{=}1.0m\)

Section: \({S}_{a}\mathrm{=}0.01{m}^{2}\)

Thickness: \(\mathit{ep}\mathrm{=}0.2m\)

Eccentricity: \(e\mathrm{=}\mathrm{-}0.01m\)

1.2. Material properties#

Concrete:

Young’s module, \(E\mathrm{=}3{10}^{10}\mathit{Pa}\)

Poisson’s ratio, \(\nu \mathrm{=}0.0\)

Coefficient of thermal expansion, \(\alpha \mathrm{=}{10}^{\mathrm{-}5}{K}^{\mathrm{-}1}\)

Steel:

Young’s module, \(E\mathrm{=}2{10}^{11}\mathit{Pa}\)

Poisson’s ratio, \(\nu \mathrm{=}0.0\)

Coefficient of thermal expansion, \(\alpha \mathrm{=}{10}^{\mathrm{-}5}{K}^{\mathrm{-}1}\)

1.3. Boundary conditions and loads#

On side \(A\) we block movements according to \(X\) and \(Z\) and the rotation around \(Y\):

\({U}_{x}\mathrm{=}0.0;{U}_{z}\mathrm{=}0.0;{R}_{y}\mathrm{=}0.0\)

On edge \(B\) we block the movement according to \(Y\):

\({U}_{Y}\mathrm{=}0.0\)

The initial temperature is \(20°C\) for steel and concrete.

The temperature of the steel is increased to reach \(120°C\).
