Il rinforzo e/o il consolidamento di pareti murarie mediante placcaggio con materiali componenti ad alta resistenza (FRP) e' divenuta una pratica professionale di grande interesse tecnico ed economico. E' stata svolta una campagna di prove sperimentali per meglio comprendere il fenomeno della delaminazione che costituisce uno stato limite della muratura cosi' rinforzata. Vengono qui riportati alcuni significativi risultati forniti da prove a trazione su elementi composti da tre mattoni e dalla loro simulazione con modelli agli E.F. appositamente sviluppati dagli Autori.

Abstract
The strengthening and the repairing of masonry walls by means of FRP materials presents great technical and economical interest. The problem at hand needs further studies concerning the necessity not only of modeling the behavior of these structures, but also, urgently, of defining suitable safety coefficients. The paper reports of experimental traction tests on simple masonry columns made by three bricks, and of their numerical simulation by F.E. models developed by the Authors.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
