Difference between Foundation Elasticity and Elastic Support

[Anonymous]

Hello, I would like to ask what is the difference between "Foundation Elasticity" in Thickness setting and "Elastic Support" in support setting.

Also, I have another question. I previously applied both "Foundation Elasticity" and "Elastic Support" at my model. I found that the result values, like shear and moment become smaller after I delete the elastic support. I am quite confused why all design value become smaller when I delete the elastic support.

If you use both they 'will add up" so your KZ will be 2* KZ instead.
