Abstract
The article presents tools for creating computational models of reinforced concrete resistance based on the concepts of "representative volume" and "characteristic zone". The tools are based on the idea of modeling zones of a structure characteristic of the type of stress state in the form of a composite strip-prism, which are described by a volume representative of the considered type of stress state, including under load-varying force flows due to crack opening-closing, shear cracks, changes in distances between main cracks, and, accordingly, changes in the stiffness of the representative volume along the three axes.
The proposed model allows determining the resistance of a reinforced concrete structure with various types of stress states in characteristic zones of the deformable space, considering the type of concrete, reinforcement classes, and specific weights of their areas, as well as considering the deformation effect during crack opening established by the author based on the fracture mechanics functional using a double-cantilever element (DCE).
Objective

Modern structures of buildings made of concrete, reinforced concrete and composite steel and concrete are in a complex stress state, which leads to a change in their strength characteristics. In the case of multiaxial compression of concrete, its strength indicators increase, which can be advantageously used in calcu...

The interfacial transition zone (ITZ) is inherently a porous region that significantly influences macroscopic mechanical and fracture behaviors of concrete materials. In this study, an extended state-based intermediately homogenized peridynamic model (IH-PD) is proposed for concrete failure analysis considering the ITZ...
