The methodology appears able to deal with practical engineering problems such as the estimate of the load- carrying capacity of RC beams strengthened by FRP sheets, issue of great significance in civil engineering. The numerical methodology may be also viewed as an useful predictive tool for estimating the actual efficacy of strengthening systems for existing structures.
