Try it with some TCL versions from the following link:

Works great for me, without any additional authentication!

Displacement control time history analysis can be carried out via ImposedMotion Command. I advise you to read the following report regarding the modeling of SPEAR building, which TCL files are also included that you can run immediately. The model includes displacement control analysis, as well as th...

In the case of asymmetric displacement values under static reversed cyclic loading, it is possible to easily define a step value between the each peak displacement in a positive and negative direction, as follows: ... set disploop [ list 0.0 0.1 -0.15 0.2 -0.24 ]; # etc, peak values of displacement ...

Same problem here, last month the server worked fine, but now I get (on Linux):

svn: E000110: Unable to connect to a repository at URL 'svn://opensees.berkeley.edu/usr/local/svn/OpenSees/trunk'
svn: E000110: Can't connect to host 'opensees.berkeley.edu': Connection timed out

Because of such problems, if someone needs the latest versions of OpenSees 64bit (for Windows machines, from 2.4.2 to 2.4.6), they can be downloaded from the following link: http://maringrubisic.com/software/OpenSees.zip

In this case, version 2.4.4. 64bit works just fine.

Reply by Michael H. Scott via e-mail, quote: "It seems you have come across a bug in the transformUtoX (and transformXtoU) functions. Basically, it is switching the order of your random variables internally, resulting in E taking on the values of P and vice versa. I’ll work on a fix. In the meantime...

I'm trying to perform a simple Monte Carlo simulation on an existing example "portalframe.tcl" available in OpenSees repository. The model is simple and clean, composed of elastic elements and also runs FORM analysis. The values of the modulus of elasticity (E) and a horizontal force (P) are defined...

Dear Michael Scott,

can you share with us the example of FORM analysis of 2-storey 2-bay RC frame from your paper "Shape sensitivities in the reliability analysis of nonlinear frame structures"? It would be a great help!

Thanks in advance!
