Engineered cementitious composites (ECC) possesses characteristics that make it suitable in the zones of high shear and ductility demand of structural elements; however, there is a lack of an adequate model to predict its shear stiffness. A theoretical model for the effective shear stiffness of reinforced ECC (RECC) columns is proposed on the basis of the truss-arch model, with the consideratio...

We present a computational modelling approach aimed at investigating the effect of fibre grid reinforcement on crack opening displacement and fatigue propagation. Grid reinforcements are modelled using elastic membrane finite elements, while cracked concrete is treated symmetric boundary element method (BEM), which in particular allows easy geometrical meshing cracks. The BEM accelerated by fas...

A multiscale (micro-macro) approach is proposed for the establishment of the full thermal and induced stress fields in cracked composites that are subjected to heat flow. Both the temperature and stresses distributions are determined by the solution of a boundary value problem with one-way coupling. In the micro level and for combined thermomechanical loading, a micromechanical analysis is empl...
