Hello <\/p>\n
I am modeling a railway track system, which consists of different concrete layers, as you can see in the pictures. The aim of the FE model is to investigate the occuring shear stresses in the steel dowels, which connect the bottom (second) concrete layer. There are dilatation gaps between the concrete plates. The plates have elastic supports with different stiffnesses (the middle plate has a soft support, at the extremities the plates have a stiffer support). The wheel loads act on the top surface of the plates….but according to the calculations I have no stresses in the dowels. Although the plates in vertical direction have different displacements due to the different support conditions. The connection between the dowels and the concrete plates I defined as a “Bounded” Connection. I expected shear stress in the dowels, as they have to compensate for vertical movements. I think the connection between the concrete plate and the dowels are not correct. Thats why I have no stresses. What is your recommendation? What shall I change? Thank You !<\/p>\n
