... columns composite structures confinement model fibre-based simulation numerical modelling Steel–concrete composite columns are a popular choice in high-rise buildings, owing to their superior strength, ductility, energy absorption capacity and fire resistance, compared with reinforced concrete...

... evolution of concrete joints under thermal action (caused by the natural meteorological environment) and vehicle loads, a two-dimensional thermal–mechanical coupled numerical model of concrete joints at the mesoscale was developed. This model analyses the influence of three factors – concrete strength...

... for RC columns. This work presents a mesoscale numerical analysis of the mechanical response of geometrically similar RC columns subjected to constant axial load and monotonic lateral load. In the numerical model, the inherent heterogeneous nature of concrete and steel/concrete interaction were...

... are important for the provision of useful data for numerical models, since these models often require the calibration of some unknown parameters according to the materials tested. To address this, the authors have developed a testing method for concrete expansion, called the alkali-wrapped concrete prism test...
