ABSTRACT
The paper presents an analysis of the impact of moving loads (road and railway) on the soil-steel bridges made from corrugated plates. Corrugated steel plate structures have been used for many years to construct culverts and small-to-medium bridges, as well as other engineering structures. The high popularity of these bridges results from advantageous technological properties, i.e. high carrying capacity, short construction time, ability to execute the works in the winter period, economic advantages (in comparison to traditional steel or concrete bridge structures), etc. The impact of moving loads was verified experimentally on a few bridges, especially by way of: (i) determining the impact of the road and railway service load on this type of bridges; (ii) determining the dynamic amplification factors and comparing the impact of the live load and analogous static load on the values of internal forces in the bridge; (iii) verifying the assumption regarding the non-inclusion of the dynamic impacts in bridges, which the soil cover thickness exceeds 1.0 m. The obtained results may be useful for professionals dealing with the soil-steel bridges and culverts.
