Simulation of the design activity diversification of innovative enterprise
Incoming article date: 11.11.2023Improving calculation models of concrete based on experimental data, especially when studying the volumetric stress-strain state, is an urgent task. When calculating the containment shells of nuclear power plants under the influence of beyond design basis accidents, it is absolutely important to take into account the available safety margins of the materials used. Under volumetric loading, due to the work of concrete in cramped conditions, its strength and deformation characteristics improve, which is not sufficiently reflected in the regulatory documentation in force in the Russian Federation. Taking into account the analysis of existing test methods, based on the labor intensity and reliability of the results obtained, the optimal method of testing for volumetric loading was identified. The article contains the results of testing the selected test method, taking into account the improvement of the deformation measurement system. They confirmed the effectiveness of using the proposed methodology from the point of view of data reliability and relatively low labor intensity of work.
