Unreinforced Masonry Structures' Seismic Improvement with F.R.C.M. : The Experience of The Vanvitellian Palazzo Murena of Perugia

The aim of the contribution is to illustrate strengthening design in regard to the conservation of Palazzo Murena in Perugia, designed in the eighteenth century by the prominent Architect Luigi Vanvitelli. Starting from an accurate historical analysis and taking into account experimental campaign and results of numerical analysis, the vulnerable elements of the construction have been highlighted. A local reinforcement intervention is proposed with the aim of retain the historical value of the architectural characteristics; this consists of the application of plaster with Fiber Reinforced Cementitious Matrix, F.R.C.M., to achieve an adequate strength, without adding supplemental weight to the masonry structure and therefore avoiding an increase of the seismic vulnerability. The benefits of the application of F.R.C.M. materials, also with respect to different reinforcement techniques are broaden
