A comparative study on stress-strain response and associated hysteresis for conventional and PET macro-reinforced concrete
https://orcid.org/0000-0002-0805-7533
Highlights Stress-strain response of conventional (CC) and PET concrete studied. Hysteresis (cyclic load) increases faster for CC than PET concrete at higher stress. Increase in lost strain energy density is slower for PET concrete than CC. Failure of CC at lower stress level as compared to PET concrete under cylic loading. PET concrete shows more ductility and performs better than CC under cyclic loading.
Abstract Present study quantifies the role of PET strips as macro-reinforcement in concrete on reducing the variation in stress-strain response and associated hysteresis under cyclic loading. The damage propagation in conventional concrete (CC) is observed to be faster than PET concrete, as confirmed by higher strain energy loss in CC as compared to PET concrete (8 and 3.5 times, respectively, when stress is increased by 50%). For both concrete, the total elastic strain recovery during cyclic loading depends on stress level; while rate of elastic strain recovery is independent of stress level. Overall, PET concrete exhibits higher ductility and better performance under cyclic loading as compared to CC.
