Abstract
In this paper the numerical FEM model developed to simulate the behaviour of the NSM
strengthening system for concrete elements is presented. The plane model introduces the non
linear bond law of the system by an interface element between the composite reinforcement
and the concrete considered linear. The results of two experimental programs are analysed and
used to calibrate the parameters of the bond shear-slip relationship by means the numerical
model. The procedure is based on the inverse analysis of the experimental data in order to
have the better fitting of the global pull-out load-displacement curves.(undefined
