Modelling post-critical deformation processes of flat reinforced concrete elements under biaxial stresses
This paper examines the issue of mathematical modelling of local destruction processes of flat reinforced concrete structures beyond design basis impacts. Analysis of the peculiarities of the local failure mechanisms, which are formed in wall concrete structures, was conducted. The paper shows that...

| description | This paper examines the issue of mathematical modelling of local destruction processes of flat reinforced concrete structures beyond design basis impacts. Analysis of the peculiarities of the local failure mechanisms, which are formed in wall concrete structures, was conducted. The paper shows that the processes of post-critical deformation of flat concrete structures occur through several mechanisms with the relevant strength criteria. The method of post-critical deformation modelling of reinforced concrete structures under biaxial stresses is proposed and justified. The modelling is conducted by the gradual change of the analysis model in the areas of failure using finite elements with stiffness parameters, which corresponds to the conditions of interaction between structure parts separated by a crack. |
