“…The purpose of experimental studies, in addition to obtaining information about the behaviour of the structure itself, is predominantly to validate the numerical model [1]. This process is about checking and possibly modifying the parameters describing a mathematical model representing a real structure to provide results similar to reality with sufficient accuracy [10,11,13]. Measured values (like displacement or strain) at various points in the real structure are checked and compared with those obtained from the numerical model at the beginning for the initial values of parameters.…”

Experimental tests and numerical simulations of a full-scale segment of a foot and cycle bridge made of polymer composites are presented in the paper. The analysed structure is made of sandwich panels, which consist of glass fibre reinforced polymer (GFRP) multi-layered laminate faces and a PET foam (obtained from recycling) core. The dimensions of the segment cross-section are the same as for the target footbridge; however, span length was reduced to 3 m.The experimental tests were conducted in a laboratory of the Faculty of Ocean Engineering and Ship Technology at Gdansk University of Technology. A single vertical force was generated by a hydraulic cylinder and was applied to the platform of the structure. The experimental tests were supported by numerical analyses performed in Femap with NX Nastran software by means of the finite element method (FEM). Results obtained in the computational model were compared with results from experiments. Thus, the numerical model was validated and the obtained conclusions were used in the next step of the design process of a composite footbridge with a span length of 14.5 m.
