In the preliminarily phase of the research, a prototype physical model has been designed with the support of numerical analyses. The experimental tests will provide reference solutions for the subsequent refinement of the numerical analyses. In this first phase they were performed numerical linear elastic analyses and incremental non-linear static equivalent analysis. This latter shows that comparing similar solutions but with different and lower strength and stiffness (Nylon ribbons), the following conclusions can be drawn. Despite the Dyneema ribbons offers better mechanical performances than Nylon ribbons the two systems provide almost the same increase of capacity; the hooping provided by both the ribbons type increases the stiffness and the load carrying capacity of the column of about 50%; the failure mode does not changes significantly from brittle to ductile, respect to the case without hooping. In conclusion, on the base of the numerical results, the proposed method shows to be effective also from the point of view of either strengthening and of easy installation and removability.
