Dynamic Identification of All-FRP Pultruded Structures

G. Boscato, A. Dal Cin, and S. Russo
Abstract—The first experimental dynamic parameters of a large spatial FRPs (Fiber Reinforced Polymers) pultruded structures are presented in this research. This construction is a temporary structure realized to accommodate future restoration work and to cover a historic church of Santa Maria Paganica stroked and partially collapsed by 2009 L’Aquila earthquake. The covering structure is an all FRP spatial-reticular with elements made by pultrusion process, connection plates by bag molding process and steel bolts. The dynamic behavior was analyzed using the ambient vibrations test to measure the mode of vibration, frequencies, displacements and damping ratios of the structures using a modal identification of output-only systems. The operational modal analysis OMA has been carried out to identify the modal characteristics through poly-reference Least Square Complex Frequency-domain (pLSFC) estimator.

Index Terms—All-FRP structures, dynamic parameters, ambient vibrations test, modal identification.
