| Title of the article | On the assessment of the maximum load of a reinforced concrete wall subjected to unilateral action of moisture |
| Abstract. | Problem statement. The reinforced concrete wall is given under the influence of the vertical axial load and the influence of moisture. It is believed that the concrete from the effects of moisture degrades over time. We assume that the strength of the reinforcement does not change with time, so we take into account the drop in strength of concrete only. The aim of the work was to develop a methodology for describing the process of degradation of reinforced concrete structures. Results. In this paper we use the law of moisture diffusion in concrete and Ficks law in the process of degradation. These equations are solved numerically by the method of finite differences. The convergence of the method of minimizing the step with respect to time and step along the coordinate was investigated. A technique for determining the diffusion coefficients is developed using the example of processing the results of an experiment for a gypsum cement-pozzolan stone. Conclusions. An engineering formula has been obtained for the determination of leached slaked lime concrete, according to which we determine the residual strength of concrete according to the work of Rakhimov R.Z. аnd Altynkis M.G. These calculations allow finding the ultimate load of the reinforced concrete wall at any time. |
