“…CFRP (carbon fiber reinforced plastics) composite materials have been recently introduced as reinforcement elements. Efficient performance of CFRP reinforcement elements have been reported in several studies [1][2][3][4]. Due to severe shear stresses separation may occur between CFRP reinforcement element and the concrete which leads to less stress transfer from concrete to reinforcement and contrariwise.…”

The effectiveness of anovel Post-Tensioned Metal Strapping(PTMS)techniqueat enhancingthe seismic behaviourof asubstandard RC buildingwas investigated through full-scale shake-tabletests duringthe EU-fundedproject BANDIT.The building had inadequate reinforcement detailing in columns and joints toreplicateold construction practices.After thebarebuildingwas initially damagedsignificantly,itwas repairedand strengthened with PTMS to perform additionalseismic tests.The PTMS technique improvedconsiderablythe seismic performance of the tested building.Whilst the bare building experienced critical damageatan earthquake of PGA=0.15g, thePTMSstrengthened building sustained a PGA=0.35gearthquake without compromising stability.

“…Ultimate displacement, Du is defined as the displacement corresponding to a 10% strength degradation of the maximum strength (Pmax) of the specimen; the yield displacement, Dy was the displacement value corresponding to the first yielding of the longitudinal beam reinforcements (LeTrung, Lee et al 2010). Generally, using the strengthening system can increase the capacity, ductility or both of them.…”

This paper presents an experimental investigation on the behavior of retrofitted beam-column joints subjected to reversed cyclic loading. The experimental program comprises 8 external beamcolumn joint connection subassemblages tested in 2 phases; one was the damaging phase and second was the repairing phase. The Beam-column joints were designed only for gravity loads. The joints had no beam-column joint transverse reinforcement and special stirrups in beam and column critical zones. These NonSeismically designed (NS) joints were damaged with different levels at the first phase of the experiment. In the second phase, the damaged joints were strengthened with externally bonded carbon-fibre-reinforced polymers (C-FRP) sheets. From the observed responses of the examined specimens it can be deduced that the technique of externally bonded retrofitting (EBR) using C-FRP sheets is appropriate for the rehabilitation of the joints seismic capacity. This technique had a significant improvement of the energy dissipation and the performance level and finally it leads to improved type of damages compared with the damage modes of the specimens during the initial loading. Shortcomings of the application of C-FRP sheets for practical use are also pointed out.
