Allowable deflection checks for steel plates / shells

[umut.akparlar]

Hello,

I am using von Mises yield criterion EN 1993-1-6 : 4.2.2 for checking steel plate yield strength checks but not sure about how to assess max allowable deflections. 

Is there a way to check allowable deflection checks for steel plates / shells using result maps? (I can access the deformation map results but not sure about how to assess them.) 

Regards

Hi @umut.akparlar 

Have you tried this?

Best regards,

Caio

Thank you Caio, I tried that too, but my question is how to decide allowable deflection value for steel shell plate. I can check the yield strength, but I also want to check deflection like L/180 value or deflection should be less than the plate thickness etc... I need that kind of a limit.

hi @umut.akparlar , 

If you are looking at a connection element / bracket / mechanical element, there is not really any SLS (service limits) requirements local to those elements e.g. when you check a beam for a L/250 limit you don't check the connections of that beam for deflection limits also. 

For such cases, you might need to rely on your engineering judgement.
