Re: SSI DIRECT APPROACH MODAL ANALYSIS

Ok so if you are working in N-mm your material density for soil is wrong
a self-weight of 18<kN/m^3> corresponds to a rho of 1.0832e-9 (g is 9806 mm/s^2)!

Re: 'NoneType' object has no attribute 'id'

You have to look at the last line of the traceback of the error.
It will tell you what element is missing a physical property

Re: Map 3D Soil Variabilities into STKO soil model

You are right, the script I sent you works for the 2D case. Here's a more generic script. It's even easier because you don't need to create sets: absorbing and soil elements will be recognized automatically from their class tag from OpenSees. base_3dmodel.zip Regarding your second problem: It will n...

Re: Beam-to-Solid-Bar-Slip

They are penalty parameters. If you make the too large you will have numerical errors. I just made them few order of magnitude larger than the typical stiffness of your model

Re: How can visualize horizontal , vertical stress in soil domain

You are right, we just realized that the combination of SSPBrickUP and a PDMY (PDMY02) material is missing some information when recording output from OpenSees. Due to this, STKO does not understand how to make the Gauss Plot. We will fix this in the OpenSees source code as soon as possible. In the ...

Re: Earth pressure along basement wall

What do you mean by "impossible when using SSPBrickUP"?

Re: SSI DIRECT APPROACH MODAL ANALYSIS

It makes sense... for such a soft soil column. Are you sure material parameters are correct?

Re: Beam-to-Solid-Bar-Slip

You can just use a smaller global mesh seed.
For this model, you should use a tetra mesh anyway

Re: How to extract the element force in fiber section

Dear STKO Team, At present, I have built two nodes at the same position in STKO, and they are connected by node to node links. I want to assign the BondSP01 material to the Zero-length section element to simulate bond slip. How to implement it in STKO, can you give a simple example? 1) Create a Fib...

Re: How can visualize horizontal , vertical stress in soil domain

If you can see the stress in the surface plot, you should be able to see it in the gauss plot as well.
From the gauss plot, you can extract the data.

If it doesn't work for you, please share more information to understand what is the issue
