Structural performance of iron-wood-FRP pedestrian bridge

this research completes the information on the structural reinforcement of a foot- bridge in Venice, whose flexural stiffness was enhanced by using GFRP (Glass Fiber Rein- forced Polymer) pultruded profiles. By inserting the composite profiles, a very good structural behavior as well as a reversible and not disturbing solution is guaranteed; furthermore, a high durability is assured by the composite material with polymeric matrix. This study highlights the benefits through all the installation steps especially granted by the low self weight of material. The structural project is then compared, through the finite element analysis, with reinforcement by traditional materials such as steel and aluminium. The final results show a very good static and dynamic performance considering the favourable ratio between mass and accidental load. The dynamic analysis was developed in the free vibrations field to control resonance phenome- na through the man-induced vibrations.
