9.1.2 Initial Values of Deformation Analysis

Initial Values of Deformation Analysis

${\rho }_e = \frac{A_s}{b · d} = \frac{4.45 {\text{cm}}^2}{100 · 20 {\text{cm}}^2} = 0.002225$

${\alpha }_e = \frac{E_s}{E_c} = \frac{200 000}{10 000} = 20.0$

$E_{c,\text{eff}} = \frac{E_{cm}}{1 + \phi } = \frac{30 000}{1 +2.0} = 10 000 {\text{MN/m}}^2$

The influence of creeping is taken into account with the final creep coefficient φ.
