Eksperimental'nye issledovaniya vliyaniya temperaturnoi relaksatsii i napryazheniya polimernykh kompozitsionnykh materialov, rabotayushchikh v sostave izgibaemykh zhelezobetonnykh elementov, pri dlitel'nom vozdeistvii nagruzok [Temperature and stress relaxation of polymer composites operating in bending concrete elements under constant load]

Purpose: The temperature and stress effects on the operation of concrete elements made of polymer composites and evaluation of their temperature and stress relaxation.
Design/methodology/approach: Modern approach to bridge structure design and mathematical statistics of the experimental data processing.
Research findings: Temperature relaxation and stress-strain curves are suggested for carbon fiber polymer composites in reinforced concrete elements under constant load.
Practical implications: Initial data for adjusting the formulas of the ultimate limited stress for calculating reinforced concrete structures strengthening with polymer composite materials.
Originality/value: The temperature drop effect must be considered in the operation of polymer composites in bending concrete elements.
