Free Vibrations of Pultruded FRP Elements: Mechanical Characterization, Analysis, and Applications

This paper shows the results of experimental tests to establish the dynamic parameters of fiber-reinforced polymer structural elements in the free vibration field. The tests and analysis consider the simply supported configuration of pultruded elements characterized by glass fiber reinforcement, glass fiber-reinforced polymer (GFRP) and the thermosetting vinylester matrix subjected to flexural, transversal, and torsional vibrations. Comparison between the experimental results and numerical analysis and the finite element method is also presented. Dynamic response of GFRP structural elements is compared with the behavior of steel and aluminum elements. The results show a good performance, especially in the case of open cross-sectional profiles, considering the advantages deriving from the ratio between the dead load and total load of fiber reinforced composite material. Finally, the use of pultruded GFRP elements for new-built decks is investigated to detect possible resonance phenomena due to human-induced periodic vibrations.
