Hi~

I have studied about soil structure interaction.

Bayram said that OpenSees Ver 1.7.5-beta works well.
whereas ver 1.7.5 is not good.

So, I'd like to use the version 1.7.5-beta..
But I can't find the version. How could I get it?

Or
I downloaded the 1.7.5 in CVS.
How could I figure out the version information...?

thanks

Frank placed the beta version of the code here some time ago
"opensees.berkeley.edu/OpenSees/code/OpenSees1.7.5.beta.zip"

BUT the latest version (v2.0.0) also supports the "update" command. I was encountering
some strange problems with v2.0.0 but Frank said that it works fine, so I downloaded the
latest version to another computer and it worked. I still don't know why it didn't work
in the other desktop computer.

The bottomline is v2.0.0 also supports "update" command.

I don't model the soil per se, I model the lateral soil springs (PyLiq1) which have p-y
curves associated with them. I include radiation damping in an approximate way (see
PyLiq1 manual) but those springs don't account for soil material damping.

As for the soil-bridge system damping I guess you could define that in the HHT integrator with alpha and beta parameters, but I'm not sure about the details of that procedure.

you need to clear your explorer cache and re-download and then install the file. your computer thinks it already has the file, so it doesn't download it again.
