摘要:Abstract(#br)Considering the heterogeneity and strain-rate effects of meso -components, concrete was simulated as a three-phase composite and a 3D meso -scale numerical method was set up. The splitting tensile failure of 315 concrete cubic samples having different side lengths wi...

摘要:Abstract(#br)Corrosion of steel in concrete structures is one of the main causes of structural durability failure. In order to study the rust cracking behavior of the concrete protective layer, a three-dimensional meso-scale model of concrete was established. In the approach, the...

摘要:Abstract(#br)This paper presents a theoretical study on the determination of intergranular and transgranular failure of mesoscale concrete under mode-I fracture. The material model for concrete is set up based on the three main meso structures, i.e. mortar, interface and aggregat...

摘要:Abstract(#br)The macro nonlinearity and size effect of concrete are essentially attributed to the internal heterogeneity of concrete. Considering the heterogeneities and the strain rate effect of meso-components, the concrete was modelled as a three-phase composite composed ...

摘要:Abstract(#br)The paper presents the results of 12 groups of geometrically similar reinforced concrete (RC) squared columns subjected to the combined loading of compression and bending. The performances and characteristics of the test RC columns are investigated in terms of the ca...
