The effect of mine induced tremors on seismic response of soil-steel bridges
Rockburst are similar phenomena like low intensity natural earthquake. They can be observed in Upper and Lower Silesia regions. Analyses of soil-steel bridges under seismic excitation are so far limited. The rockburst is related to the mining exploitation. The influence of rockburst on the soil-steel bridges should be investigated, because this ground motions differ with many respects from natural earthquakes. The span of soil-steel bridges is typically range from 3 to 25 m, so they can be used as an effectives alternative for a short-span bridges. The soil-steel bridges can meet the design and safety requirements similar to traditional bridges, at lower costs. For these reasons, soil-steel bridges are more frequently used in road and railway projects in many parts of the World. This paper presents results of numerical study of soil-steel bridge under rockburst induced ground excitations. Response characteristic axial of the soil-steel bridge caused by rockburts are analysed in detail. The obtained results are compared with the ones computed under El Centro using the seismic benchmark record.
