sub-grade reaction Kz

[saraingenieur]

Hi ,

please i need a help.

I would like model the sub-grade reaction ks =450t/m3. i must define kS in elastic support or in panel thickness or in the both. and if i defined Ks in elastic support and in panel thickness  ,the robot will take ks=900 T/m3.

please help me.

Not both at the same time.

I suggest you to use panel thickness as you'll can get results (displacements, reactions) in maps.

thank you for your answer,

 but if i define the sub-grade reaction  just in panel thickness i have this message "No supports" .

what can i do?

Thank you.
