The considered process of long-term deformation of reinforced concrete under varying external load conditions is based on the integral estimation method of deformation resistance, which relies on the use of integral deformation modulus. A method for calculating a reinforced concrete frame on a soil base in aggressive environment under the conditions of rheological deformation has been developed, which reflects the real operation of structural elements under the combined influence of force and non-force factors based on the modern phenomenological theory of deformation of an elastic creeping body. Long-term operation of a reinforced concrete frame on a soil base, taking into account corrosion damage, is evaluated. An example calculation of a reinforced concrete frame of a building on a soil base is given for various operation periods and the presence of corrosion damage. It is shown that damage due to exposure of reinforced concrete structures can affect the strength of the material, change the calculation models, redistribute stresses in the cross-sections of the structure and also lead to other consequences that reduce the design life of buildings.</p></abstract><trans-abstract xml:lang="ru"><p>Исследована возможность расчетными методами еще на этапе проектирования конструктивных элементов различных сооружений из железобетона учитывать учесть длительность эксплуатации, нелинейность и реологию деформирования используемых материалов, а также принимать во внимание возможные коррозионные повреждения, что позволит определять размеры поперечных сечений и назначать требуемые классы бетона и арматуры. Рассматриваемый процесс длительного деформирования железобетона при изменяющемся режиме действия внешней нагрузки основан на методе интегральных оценок сопротивления деформированию, в основу которого положено использование интегрального модуля деформаций. Разработана методика расчета железобетонной рамы на грунтовом основании в агрессивной среде в условиях реологического деформирования, отражающая реальную работу конструктивных элементов при совместном воздействии факторов силового и несилового характера на основе современной феноменологической теории деформирования упруго ползучего тела. Представлена расчетная оценка длительной эксплуатации железобетонной рамы на грунтовом основании с учетом коррозионных повреждений. Приведен пример расчета железобетонной рамы здания на грунтовом основании при различных сроках эксплуатации и наличии коррозионных повреждений. Показано, что средовые повреждения железобетонных конструкций могут повлиять на прочность материала, изменить расчетные схемы, перераспределить усилия в сечениях конструкции, а также привести к другим последствиям, которые снижают проектные сроки эксплуатации зданий.</p></trans-abstract><kwd-group xml:lang="en"><kwd>design scheme</kwd><kwd>building structures</kwd><kwd>corrosion damage</kwd><kwd>service loads</kwd><kwd>stresses</kwd><kwd>deformations</kwd><kwd>rheological properties</kwd><kwd>nonlinearity</kwd><kwd>operation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>расчетная схема</kwd><kwd>строительные конструкции</kwd><kwd>коррозионные повреждения</kwd><kwd>эксплуатационные нагрузки</kwd><kwd>напряжения</kwd><kwd>деформации</kwd><kwd>реологические свойства</kwd><kwd>нелинейность</kwd><kwd>эксплуатация</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Bondarenko V.M., Kolchunov V.I.
