В связи с усложнением строительных конструкций, повышением уровня и вариативности их нагружений задача определения точных значений деформаций в них является актуальной. В материалах конструкций деформации неразрывно связаны с напряжениями, от уровня которых зависит прочность и безопасность эксплуатируемых зданий и сооружений. Процессы развития деформаций достаточно сложны и зависят от многих факторов, при этом для их регистрации при испытаниях строительных конструкций чаще используют один из известных методов, каждый из которых имеет свои преимущества и недостатки. Для получения более полной картины процессов развития деформаций и трещин в железобетонном элементе представляется перспективным совместное применение этих методов. Цель работы — повышение прочности и надежности железобетонных элементов путем комплексного анализа развития процессов деформирования и трещинообразования с использованием методов электротензометрии, корреляции цифровых изображений и регистрации тепловых выделений. Разработана методика комплексного экспериментального анализа и проведены пробные испытания железобетонного образца на растяжение с получением данных о деформациях тремя методами — с использованием тепловизора, системы Vic-3D и тензорезисторов. Представлены полученные опытные данные и проведен их комплексный сопоставительный анализ. Отмечены преимущества и недостатки предлагаемого подхода. Намечены дальнейшие пути развития предложенной методики.

When designing building structures, due to the increase in their complexity, level and variability of loads caused by the development of industry, the task of determining the exact values of deformations is relevant. The values of deformations are inextricably linked with the values of stresses in structural materials, the level of which determines the strength and safety of buildings and structures in operation. The processes of deformation development are quite complex and depend on many factors, while one of the known methods is more often used to register them during testing of building structures. Each of these methods has its advantages and disadvantages, and an integrated approach with their combined application allows you to get a more complete picture of the processes of deformation and crack development in a reinforced concrete element. The purpose of the work is to increase the strength and reliability of reinforced concrete elements through a comprehensive analysis of the development of deformation and cracking processes using electrotensometry methods, digital image correlation and registration of thermal emissions. Research methods: experimental studies, digital image correlation method, thermal imaging method, strain gauge method. Results: A methodology has been developed, test tensile tests of a reinforced concrete sample have been planned and carried out to obtain deformation data using three methods using a thermal imager, a Vic-3D system and strain gages. The experimental data obtained are presented and analyzed. A comprehensive comparative analysis of the results obtained was carried out, the advantages and disadvantages of the proposed approach were identified. Further ways of developing the proposed methodology are outlined.
