Strain Stress

В настоящее время для трубопроводных систем разрабатываются виброизолирующие конструкции на основе резинокордных оболочек. Основная роль компенсирующего патрубка - это исключение передачи усилий от действия давления рабочей среды в полости трубопровода на фланцы и присоединяемые механизмы. Для оценки прочностных характеристик резинокордного патрубка на основе численного исследования используется трехмерная модель, армированная балочными элементами. В результате проведен расчет напряженно-деформированного состояния резинокордной оболочки и фланцевого соединения патрубка. Определенные аспекты исследования необходимо учитывать при проектировании и эксплуатации конструкций патрубков на основе армированных оболочек.

Introduction. Considering that reinforced concrete is the most common material in construction and reconstruction of buildings and facilities, research of work of high-strength reinforcement in reinforced concrete elements, including compressed columns, are still relevant at present. Analysis of compound-section columns with high-strength longitudinal reinforcement is of particular interest since the method of sectional build-up is widespread enough in the reconstruction of buildings and facilities. However, no information on the work of this kind of reinforced concrete structures under long-term compression was found either in foreign or domestic literature; this fact provides relevance and academic novelty of the study. Materials and methods. The article provides the research of parameters of the strain-stress state of compound reinforced concrete bars with high-tensile reinforcement under long time compression employing the modern methods of mathematical simulation. Results. The developed calculation method allows determining additional parameters of the strain-stress state of the compressed compound-section reinforced concrete bars considering the concrete creep deformations forming in time of the long-term compression. When comparing the analytical study results with authors’ experimental data and previous results of other researchers, an adequate degree of reliability of the developed calculation method was confirmed. Conclusions. When applying the developed calculation method of stress-deformation state parameters for the compressed compound-section columns with high-strength longitudinal reinforcement, the study discovered that significant effort redistribution from concrete to high-strength reinforcement occurs under long-term compression. This fact was confirmed with the results of an experimental investigation on the resistance of the compound reinforced concrete bars with high-tensile reinforcement to the longtime compression.
