چکیده
Yielding of longitudinal rebars in reinforced concrete (RC) elements leads to the localization of damage and consequently increases repair costs. Two options are available to mitigate this localization in rebar strain: the use of debonded-steel rebars or Glass Fiber Reinforced Polymer (GFRP) rebars. An experimental program was devised, including three specimens with steel, debonded-steel, and GFRP rebars. There is a bold change in the crack pattern, from localized in the case of steel rebar with a crack width of 35 mm, to distributed cracks in the cases of debonded-steel and GFRP rebars, with a crack width smaller than 3 mm. This indicates a significant improvement in terms of repairability for these specimens. The failure drifts of the specimens are 3.5%, 3.5%, and 5.5%, respectively. Results also show that the debonding of steel rebars increases energy dissipation. This demonstrates that by following current practices in the design and construction of RC elements, and simply by debonding steel rebars, it is possible to decrease repair costs.

تازه های تحقیق
  • Cyclic loading of RC beam with and without steel tube around longitudinal reinforcement in plastic hinge zone carried out and Comparing specimens shows that by debonding the steel rebar it is possible to develop more desirable energy dissipation behavior.
  • In a concrete beam, GFRP rebar was used as the main reinforcement, and no buckling was observed in the GFRP rebar in cycle 12 with an applied displacement of 122 mm. In contrast, in the concrete beam with steel rebar, the steel rebar buckled in cycle 9 with a displacement of 70 mm.
  • Concrete beam reinforced with GFRP rebar exhibited larger deformations and forces compared to concrete beam reinforced with steel rebar, but the GFRP-reinforced beam displayed lower energy absorption capacity.
