Influence Functions of Shell Deflection in Soil-Steel Bridges
Journal of Traffic and Transportation Engineering
This paper analyze the effects of loads changing position on the soil-steel structures made of corrugated plates. The analyzed quantity is the shell deflection depending on the location of vehicles. On this basis, the influence functions of deflection are determined. On the basis of results of tests conducted on numerous soil-steel structures, it has been proved that the deflection influence line, which is commonly used in the static analysis of bridges, can not be obtained for this type of
... ctures. This is due to the form of deflection and deflection differences that occur during a primary passage and a secondary (return) passage of the moving load. The deflection influence functions analyzed in the paper are used to determine the stiffness of classic beam bridges, masonry bridges and soil-steel structures. This allows to conduct comparative analyses of different groups of bridges (road bridges, railway bridges, pedestrian bridges), using results of the tests performed under the service load.
