Re: Zero length elements with shear-axial interaction

as far as I know - none has ever received the code.

But looks like many users are interested - perhaps it could become part of the standard OpenSees material library?

unloading/reloading issue with Hysteretic material

Hi all, I am running Time-Histories on SDoF model with 1 transnational spring with the Hysteretic material (see source code below by signature). I've realized something strange in the output hysteretic curves: -in the non-linear range, after the unloading, the reloading shows "jump" of forces (almos...

Add your own code

Hi all,

I am following the video about how to add my own code to opensees. in the video everything (visual studio and opensees) is set to x32, but I ve got a x64 machine.

Are in this case different steps to be taken?

Cheers,

Source code link does not work

Hi all,

The source code link in the opensees webside does not work for me.

Is it the same for you?

Can someone please attach the current link of the source code?

Cheers,

Self-centering with asymmetric backbone

Hi all, I trying to model a rocking behavior with non-lin rotational springs. The flag-shape model (Self centering) is the way to go, but I would need to have different yielding force in the 2 direction. Has anyone worked in something similar? Suggestions in an eventual coding procedure? Cheers,

Re: How to extract absolute acceleration

I myself did it in the post processing phase... summing up (python script or even excel) the values of the accel nodal recorder (relative) with the GM accelleration values, making sure that the time-step of the two is the same. It worked fine!

Re: Large Accelerations during gravity analysis

Why do you wanna use transient for gravity?

I usually for static, based on the example I found in opensees wiki.

Have you seen them? like dynamic analysis on 2d steel frame
