This paper presents the main results obtained during a long and intensive research period on the modelling of the main physical mechanisms related to damage and fracture of concrete. The starting point has been the Mazars one scalar damage model[...]

The present contribution aims at providing a closer insight on boundary effects in non local damage modelling. From micromechanics, we show that on a boundary interaction stress components normal to the surface should vanish. These interaction s[...]

The aim of this paper is to present a modelling of mechanical behaviour of concrete on a mesoscopic scale. Concrete is considered as a bi-phasic material where the cement paste and the aggregates are described with their own mechanical character[...]

This study focuses on identifying concrete behavior under severe loading (near field detonation or ballistic impacts). In order to reproduce high stress levels with wellcontrolled loading paths, static tests are carried out on concrete samples b[...]

Three simplified modelling strategies are proposed to simulate the non linear behaviour of reinforced concrete (RC) structures submitted to severe loadings. The Equivalent Reinforced Concrete model (ERC) is suitable for very squat RC walls and i[...]

The seismic behavior of reinforced concrete structures is generally evaluated through modal spectral approaches, based on linear elastic analysis. In the case of seismic reevaluation of existing structures using traditional methods, since the no[...]

In this paper, it is presented the study of the inelastic seismic response of the 3storey irregular SPEAR building, which was pseudodynamically tested under bi-directional seismic excitations at the ELSA Laboratory of the Joint Research Centre. [...]

Continuum damage mechanics allows accounting at the representative elementary volume for microcracks growth. Nowadays, describing the mechanical behavior of corroded structures remains of primary importance, especially when optimal maintenance p[...]

We introduce a model for calcium leaching and creep strain evolution. Both phenomena are coupled for the estimation of the damage time evolution. Simulations are achieved so as to quantify the influence of the input parameters variability on the[...]

Short and long-term behaviors of concrete structures are of importance when dealing with durability aspects. One particular interesting aspect is the change in microstructure of concrete submitted to drying or leaching processes, and a potential[...]
