Valorization of various grillage models of underpass based on field test

In this paper, the valorization of two different planar grillage models was conducted using the results of load testing carried out on underpass Vrata 1 on highway Zagreb - Rijeka, sector Vrata - Delnice. The valorization was conducted comparing the transverse distribution of measured and calculated deflections for different load schemes applied during the field test. On the basis of conducted analysis, it is recommended which of the two analysed models should be used for analysis of the ribbed bridge decks with transverse girders over supports and in the middle of the span.
