| Abstrait: |
Strengthening Reinforced Concrete (RC) columns using jackets is a common technique used for the seismic upgrade of existing structures. In this study the effectiveness of traditional RC jacketing techniques is compared with the use of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) for the seismic upgrade of existing elements. Numerical models have been developed using ATENA Finite Element Analysis (FEA) and a parametric study has been conducted taking into account normal concrete to UHPFRC interface, and the differential shrinkage effect. The results of the parametric study indicate that the use of UHPFRC can considerably improve the strength and the stiffness of existing reinforced concrete columns. |
