Fragility curves method: a simple procedure in the structural lifetime prediction, The

As well know, during their service life structures, if subjected to aggressive environments or to their heavy dead loads, suffer degradation of their component materials. Such damages could decrease the mechanical characteristics of the system, and, along with them, even its reliability. In order to deal with these aspects, an approach based on fragility curves is proposed. The proposed method is applied on sets of experimental data concerning the deterioration of concrete structures immerged into aggressive environments and the long term behavior of a historic masonry subjected to their heavy dead load. At last, a first validation of the methodol-ogy is approached.
