Abstract

In this work the attention is focused to the numericalsimulation of the experimental bending tests carriedout on a total of six reinforced concrete r.c. plates thelatter aimed to provide a basic understanding of the its performancewhen strengthened by Fiber Reinforced CementitiusMatrix (FRCM) Composites. Three of those were usedas control specimens. The numerical simulation was carriedout by LUSAS software. A good correlation betweenthe FE results and data obtained from the test, both in theload–deformation behavior and the failure load was highlighted.This permits to prove that applied strengtheningsystem gives back an enhancement 2.5 times greater in respectof the unreinforced case. A greater energy dissipationability and a residual load-bearing capacity makes theproposed system very useful in the retrotting as well asin the case of strengthening of bridge structures. Based onthe validation of the FE results in bending, the numericalanalysis was also extended to characterize the behavior ofthis strengthening system in tensile.
