Numerical simulations for the determination of chloride diffusivity in reinforced concrete under tensile load

In service conditions, reinforced concrete structures are multi-cracked due to the loads they are submitted to. It enables aggressive agents, such as chlorides, to penetrate the concrete cover and could initiate steel rebar corrosion leading to more…

Méthodologie pour l’évaluation du coefficient de diffusion des chlorures dans le béton armé sous chargement de traction

L’exposition à un environnement marin ou à des sels de déverglaçage est à l’origine de phénomènes de corrosion des armatures dans les structures en béton armé : les chargements mécanique, thermique et/ou hydrique entraînent effectivement la…

Isotropic and anisotropic Eikonal gradient-enhanced damage models: thermodynamics derivation and simulation of quasi-brittle materials

Quasi-brittle materials are often modeled using strain-softening continuum damage models. This implies using the so-called regularization techniques to obtain mesh-independent results in a finite element context. Non-local models of integral [1] and…

Bidirectional real-time hybrid test on a steel column virtually connected to a reinforced concrete substructure

This paper presents the results of a bidirectional Hardware-in-the-Loop (HiL) realtime hybrid test on a steel column connected to a two-story reinforced concrete (RC) substructure under earthquake conditions. Two hydraulic dynamic actuators apply…

Comparison of POD-UDEIM and POD-ECSW model order reduction in the case of damaging RC structures subjected to earthquakes

This paper uses Hyper-Reduced Order Models (HROMs) to accelerate parametric and sensitivity analyses on reinforced concrete structures subjected to earthquakes. The number of Degrees Of Freedom (DOFs) is reduced using a Proper Orthogonal…
