design offshore contaienr

[benzarti.helmi]

I'm new in using Robot Structural Analasys and I want to design an offshore container in particular offshore basket ( container without roof) 
the dimensions of my basket is 20' x 8' x 5' (6096mm x 2440mm x 1520mm) with a payload = 10 tonnes

I have a diffculty in representing lifting forces ( = 2,5 x 10 tonnes x 9.81) and in dimensioning the container structure: I have an error message ( erreur de type 3 dans la noeud 12) and in dimensioning the container structure an other error  ( la vérification des barres au déversement n'a pas été effectuée. Ces types de section ne sont pas prises en compte par la norme ou ne nécessitent pas de vérification spécifique au déversement) 

please I need help like I said I'm still not familiar with Robot structural Analysis. thanks in advance

Hello Benzarti,

I dont know what you want to calculate but you need to add support to your structure, see attachment.

Benzarti,
I believe that your problem is boundary condition for lifting. Try DNV 2.7-1 , Appendix C - it will give you way how to support lifted containers (elasticity of supports). http://www.dnv271containers.com/DNVContainerStandard2-7-1/DNVContainerStandard2-7-1.pdf
