The success of Fiber Reinforced Polymer (FRP) composites for the strengthening/reparation of concrete structures is due to a favorable combination of suitable properties, superior than those of traditional materials, and manufacture/ installation capability. Of great importance is the behavior of the repaired structure under loading and its durability in the outside climate. The lack of fundamental knowledge on their longterm behavior and of specific standards for durability investigation makes difficult the assessment of reliable theoretical models, hampering their extensive use in construction. The analysis of durability of FRP’s, in terms of their degradation causes and mechanisms, is a critical issue for their safe implementation in concrete structures.

Abstract
The success of Fiber Reinforced Polymer (FRP) composites for the strengthening/reparation of concrete structures is due to a favorable combination of suitable properties, superior than those of traditional materials, and manufacture/ installation capability. Of great importance is the behavior of the repaired structure under loading and its durability in the outside climate. The lack of fundamental knowledge on their longterm behavior and of specific standards for durability investigation makes difficult the assessment of reliable theoretical models, hampering their extensive use in construction. The analysis of durability of FRP’s, in terms of their degradation causes and mechanisms, is a critical issue for their safe implementation in concrete structures.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
