Abstract
Results of an experimental testing program on two beam-column connections at full scale are presented. Specimens were first tested without initial damage. After that, rehabilitation was conducted using two different techniques, namely: externally bonded carbon fiber reinforced polymer and ultra-high performance mortar reinforced with steel fibers. Specimens were then re-tested. Different loading protocols were used on each specimen to assess their impact on the load-deformation capacity. Such protocols were displacement-controlled and applied quasi-statically. Performance of the specimens, before and after rehabilitation, is presented and discussed in terms of strength and drift capacity, energy dissipation, equivalent viscous damping, effective stiffness, cracking, and visual damage. Interesting findings, useful for the rehabilitation of concrete structures after strong earthquake ground motions, are presented.
