14 STRUCTURAL REINFORCEMENT AND SEISMIC RETROFITTING WITH UHPFRCC SPECIAL FORMULATIONS JACKETING In recent years the strengthening and the repair of existing RC structures have been among the most important challenges in civil engineering. The primary reasons for strengthening of structures include : upgrading of resistance to withstand underestimated loads ; increasing the load-carrying capacity for higher permit loads; meet the requirements in seismic areas where older construction were not designed for earthquake actions; restoring lost load carrying capacity due to corrosion or other types of degradation caused by aging, etc. In this field the possibility of increasing the bearing capacity of RC elements under shear actions is of great interest, due to a high probability of having structures lacking in shear reinforcements. REFOR-tec formulations, corrosion and fire resistant, having a hardening behaviour in tension (strain hardening), offer major advantages if compared to other reinforcement systems like externally bonded steel plates, large thickness R.C. jackets, externally bonded fibre-reinforced polymers (FRP). Hundreds of REFOR-tec technology applications succeeded in Important Structural Reinforcements and Seismic Retrofitting Projects starting since early 2000.
