Abstract
The modelling of soil-structure interaction is of crucial importance for the design of flat founded reinforced concrete crane beams. The resulting stresses on the crane beams depend on the ratio of the bending stiffness of the crane beam and the stiffness of the soil.
The real stiffness of the crane beam can be determined realistically by using non-linear material models. The stiffness reaction of the soil is usually modelled by a subgrade reaction modulus.
This article shows a way of estimating a temporal change in the subgrade reaction modulus under cyclic loading by means of in-situ tests and additional geotechnical calculations and transferring this to the geometry of the crane beams by defining a subgrade reaction factor.
The influence of the variable subgrade reaction modulus due to cyclic loading on the design of flat founded crane beams is illustrated in a calculation example. The example relates to crane beams of gantry cranes in container handling.
