ABSTRACT
One of the characteristic features of steel-soil structures in comparison to classical bridges is the impact of the surrounding soil and the road superstructure for its bearing capacity. In this paper based on the in-situ test it is proved that the results of analysis are sensitive of the direction of live load vehicle. For this purpose, the methodology, where the vehicles change their positions was used. Both in the test and the analysis, the full load cycle was carried out, including the drive of the vehicle in two directions, i.e. from the starting position to the turning point and back. A special feature is structure tendency to reaching the primary readings after full cycle of loading. This proves an elastic behavior of soil-steel structure, which is especially important where the one of the basic structural material is the soil (in the classical arch bridges treated as a non-structural).
