Evaluation of energy retention capacity of composite CFRP and GFRP in RC beam strength, vol.8, no.2, pp.1-29, 2022 (Peer-Reviewed Journal)
Energy dissipation capacity and ductility are two significant parameters to
improve structural performance in construction. Although there are many
traditional methods of strengthening studies of beams are strengthened with
fiber polymers draw attention, especially in recent years. In this study, the
strengthening of the beams by the externally bonded reinforcing (EBR) method
are investigated. The current studies in the literature are comprehensively
reviewed and significant results have been presented. The energy dissipation
capacities and ductility values of the important forty CFRP-GFRP beam
strengthening studies of the last 10 years have been determined as nearly value
based on the load-deflection graphs. The results are given in the table, and the
accuracy hypothesis of the mean values of the two groups are statistically made
with usage of the T-test. The values were chosen from within the acceptable
range to increase the accuracy of the T-test. The average of the selected ultimate
load values is very close to each other, CFRPs have also slightly higher load
carrying capacity than GFRPs. When it comes to ductility analysis with T-test, it
is seen that GFRPs have higher ductility values.
