description: An updated assessment of the impact of temperature and humidity gradients on the stress and strain state of the reinforced concrete structures of the cooling tower will make it possible to develop recommendations for increasing the durability of reinforced concrete cooling towers taking into account the peculiarities of the influence of temperature and humidity effects. This will allow JSC Atomenergoproekt to reduce the volume of materials used and reduce the cost of technical repairs and maintaining the cooling tower in proper operational condition during its operation. The purpose of the study is analysis of the influence of variable temperature-humidity conditions on the stressed-deformed state of the shell of the reinforced concrete tower cooling tower and development of recommendations for increasing the durability and strength of reinforced concrete cooling towers taking into account the peculiarities of the influence of temperature-humidity effects. Tasks that were solved during the research: 1. Perform analysis of methods of calculation and researches results of reinforced concrete tower cooling towers of domestic and early-start construction; 2. Develop a spatial model of the reinforced concrete cooling tower, complete the collection of loads and impacts on the structure; 3. Calculate the forces and deformations of the reinforced concrete shell from the specified loads, determine the contribution of temperature-humidity gradients to the stress and strain state of the structures; 4. Assess the impact of additional forces in the structural elements on the stress and strain state of the cooling tower shell; 5. Develop recommendations to increase the durability of reinforced concrete cooling towers taking into account the peculiarities of the influence of temperature and humidity actions; The graduation thesis was carried out on the basis of the initial data provided by JSC Atomenergoproekt, including: geological survey data, weight and size characteristics and parameters of the cooling tower, manuals and survey results. A new PATRAN software package for calculating the forces and deformations of the reinforced concrete shell of the cooling tower was mastered, the stress and strain state characteristics of the shell of the reinforced concrete cooling tower were calculated, the contribution of temperature- 8 humidity gradients to the stress and strain state of the structural elements was assessed, and recommendations were developed to increase the durability of the cooling towers taking into account the peculiarities of the influence of temperature-humidity effects. Recommendations were also developed to improve the durability of reinforced concrete elements and structures of the cooling tower exhaust towers, namely, the use of a multi-component complex additive for polyfunctional, plasticizing, air-entraining concrete and the arrangement of waterproofing coatings that meet the operating conditions of the structures. The option of erecting a reinforced concrete cooling tower with an anticorrosive coating of an acrylate and copolymer-based shell reduces operating costs by 27% compared to typical design solutions.
