Zheng et al [26] improved the micropolar peridynamics model by considering concrete materials' low tensile strength and high compressive strength and weakened the interaction between rebar and concrete in reinforced concrete structures. Zhang et al [27] and Zheng et al [28] coupled PD with an atomistic (AM) model and classical continuum mechanics (CCM) model, respectively, which guaranteed accuracy and enhanced computational efficiency.…”

A reinforced concrete shear wall is an important building structure. Once damage occurs, it not only causes great losses to various properties but also seriously endangers people’s lives. It is difficult to achieve an accurate description of the damage process using the traditional numerical calculation method, which is based on the continuous medium theory. Its bottleneck lies in the crack-induced discontinuity, whereas the adopted numerical analysis method has the continuity requirement. The peridynamic theory can solve discontinuity problems and analyze material damage processes during crack expansion. In this paper, the quasi-static failure and impact failure of shear walls are simulated by improved micropolar peridynamics, which provides the whole process of microdefect growth, damage accumulation, crack initiation, and propagation. The peridynamic predictions are in good match with the current experiment observations, filling the gap of shear wall failure behavior in existing research.

Reinforced concrete structures experience crack propagation, bond‐slip, and accompanied stress redistributions when subjected to high loading levels, as a typical continuous–discontinuous process. This work proposes a numerical system composed of discrete blocks, springs, and one‐dimensional bolt elements within the continuous–discontinuous element method (CDEM) framework. This hybrid finite‐discrete element method is enhanced by explicit integration. By simulating the pull‐out tests, the mechanical interactions between bars and concrete are determined. Numerical studies demonstrate the effectiveness of the proposed method in capturing the process of multiple crack propagation and bond‐slip in three‐dimensional reinforced concrete structures, such as columns and beams.
