WP 4 deals with bridge strengthening by externally bonding reinforcement. Its objective is to elaborate guidelines and procedures for structure elements strengthening with prestressed Fibre Reinforced Polymer (FRP). The prestressing process may bring an intense increase in strength with the use of FRP material effectiveness. Deterioration of bridge structures is one of the major problems the new member states are facing today. The necessity of bridge strengthening was caused by the change of load conditions, which appeared in the last twenty years as well as the material deterioration. Steel plates and composite materials give a great opportunity of bridge strengthening. |
