摘要：
The paper contains analysis of full-scaled three meters long segment of a novel composite footbridge. Both numerical modeling and experimental validation were performed. Analyzed object is a shell type sandwich channel-like structure made of composite sandwich with GFRP laminates as a skin and PET foam as a core. Several static load schemes were performed including vertical and horizontal forces. In FEM analysis multilayered laminate was modeled by means of Equivalent Single Layer (ESL) method while the foam was assumed as three-dimensional continuum. Results were compared with the ones obtained from experiments. Good agreement in comparison showed the correctness of conducted assumption what was a great support in designing process of fourteen-and-half meters long footbridge.
