Excavation problem

Post by yuweihwang » Wed Jan 06, 2021 4:20 am

Hello,

I have a problem is to excavate a tunnel. Is that possible to use STKO to do the following analysis?
1. do static equilibrium for the entire soil profile first.
2. excavate a rectangular shape tunnel
3. do static equilibrium again

Many thanks for your kind help

Dear Yu-Wei,

We are currently implementing it as a built-in command in STKO.
In the meantime you can use a custom script as shown in this example file:

To do this, you need to use this new updated "region" command, place it in
"C:\Program Files\STKO\external_solvers\opensees\analysis_steps\Misc_commands"
replacing the existing one
region.zip
