Abstract
A brief review of foreign and domestic theories or criteria for concrete strength, modern proprietary and “heavy” software and computing systems for solving reinforced concrete problems in a 3D solid nonlinear formulation is provided. The concrete strength criteria used in these systems are listed. The Menetrey-Willam plastic flow theory of concrete is examined in detail, taking into account the possibility of nonlinear hardening under compression and linear and nonlinear softening under tension and dilation (HSD).
Numerical modeling of three different fragments of slab reinforced concrete structures was carried out using the finite element method (FEM) in the ANSYS 2024 R2 software package with variations in the following: FE dimensions, strength criteria, reinforcement method and HSD parameters, and reinforcement area. The results of slab calculations are described in detail, with quantitative and qualitative characteristics of the calculation models indicated. Ways to improve the FEM for calculating slab reinforced concrete structures are proposed.
Existing engineering methods for calculating monolithic reinforced concrete walls do not provide the desired accuracy and fail to take into account significant factors due to inherent simplifications This drawback can be eliminated by applying FEM-based computer modeling in one of the «heavy» computing complexes of the...
