Abstract
A framework for applying nonlinear finite element analysis to assess the current and future condition of reinforced concrete infrastructures has been established. It proposes two approaches for composing material models applicable for that purpose. Both approaches open for either composing available material models or by programming them as user supplied subroutines in commercial general purpose finite element software. Furthermore, methods to account for material degradation due to alkali silica reaction and reinforcement corrosion were formulated along with a safety format applicable for that purpose.
