ABSTRACT
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 structures. 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.
