hello,

have you found the reference source code?

Zero length elements with shear-axial interaction

Hi all, Is there anyone who attempted to create within a frame model, zero length translational and rotational springs in which the F-d (or M-rot) relationship depends on the axial load of the beam elements? For instance, I am thinking about a moment frame with concentrated plasticity, in which the ...

I did try that approach, but, as you said ( and as expected) I get convergence issues.

Get a plot with hysteretic curve of the structure

Hi all,

is there a fast way to get a plot (recorder command) directly at the end of the analysis the force displacement curves for all the piers?

Cheers,

plot windon crash

I am using the following command:

recorder plot Node3.out "Nodal displacement" 10 10 400 400 -columns 1 2

to plot data from a file I have alrady produced priorly, but the window open and crashes before displaying, everytime. and then I need to close opensees.

which could be the reason?
