Two RC beam specimens were casted; the first beam is used to serve as a control specimen while the second was strengthened with GFRP NSM bars reinforcement. The two beams were tested under cyclic loading up to failure of the specimens. Then, a 3D Finite Element (FE) model that integrate different nonlinear constitutive material modeling laws and techniques such as concrete cracking, steel yielding, and imperfect bonding was developed using the finite element code ANSYS. The imperfect bonding captures the bond slip behavior between the NSM reinforcement and concrete surfaces. In addition, the developed FE models were validated against the experimental tests via a comparison of the load-deflection response envelopes and hysteresis loops. A Good matching between the experimental results and FE simulation were observed. Further experimental testing and numerical validation will be carried out in a future extensive research study to further investigate the performance of such systems when subjected to cyclic loading as in a seismic event.
