orthotropic bridge deck
orthotropic bridge deck
(OP)
Hi,
I need examine normal stresses of orthotropic railway bridge deck (i mean thin flange with stiffeners perpendicular to this flange). I am interested in stresses on interface flange - stiffeners as well, so I need know their correct values. But discontinuity of these stresses occur on this interface...
I work in ansys9 and use shell 181 member.
Is there anyone able to help me avoid this discontinuity and obtain correct values ?
p.s. : sorry for my bad english, but I hope it is clear...

RE: orthotropic bridge deck
Two opposite edges (edges of stiffeners are included as well)are subjected to uniform pressure - it means load is
applied in mid-plane of shell elements.
There is used initial geometrical imperfection of thin-walled sheet in shape of sinusoidal surface (initial stresses are not considered)
