Performance of the FRPC rehabilitated RC beam-column joints subjected to cyclic loading

摘要: This paper discusses both experimental and analytical investigations for evaluation of the performance fiber reinforced polymer composites (FRPC) rehabilitated concrete (RC) beam-column joints subjected to cyclic loading. For investigations, two types joint specimens, with ductile brittle reinforcement detailing are cast investigated in this study. The specimens displacements increasing amplitude until failure. Post failure, using FRPC. rehabbed then similar regime Salient details procedures preparation investigation control discussed paper. Performances recorded form load-displacement plots. Comparisons between performances highlight efficiency rehabilitation scheme enhancement strength, ductility, deformability RC joints. In relationships modeled multi-scale models which consider stiffness degradation under Accordingly, also reports brief discussion on stepwise development materials; cross-section; that Good agreement experimentally observed analytically relations facilitates validation models, provides useful means field applications FRPC
