You don't have to use fiber sections. You can, for example, use a section aggregator inside a force-based element. https://portwooddigital.com/2021/07/04/you-gotta-keep-em-aggregated/ Hello, Thank you for the link. I just interest in static analysis, so I think i do not need hysteresis as in the li...

Hi, I need to analyze a structure consist of armed concrete beam and columns (say for example single span single level frame at simplest form) Need static nonlinear (both material and geometrical non-linearity) analysis . I'm aware of fiber element, which could be used to model material non-linearit...

I've found the problem. I was applying nodal load to a fixed node .
This is correct code and correct output:

Thanks anyways...

Hello, I'm trying to model a single ShellDKGQ file with c++, here is my code: https://gist.github.com/epsi1on/9a671b853f3c024c9bb0fb86602691b5 My problem is after solve i do get zero displacement on nodes and loads stays unbalanced (output from above code): https://gist.github.com/epsi1on/b2ff22c0ea...

What parameters are allowed to use for this element with element recorder? Currently i'm using this command on a model with all elements of type ShellDKGQ : recorder Element -xml "elm.xml" -time -closeOnWrite stresses to get stress values in Gauss points in all element and write them into ...

Hi,
I have worked with C#.net briefly in several years and I think having Opensees .NET Framework interface (or CPP/CLI) would be quite useful and popular.

Thanks

i was able to export global stiffness matrix of whole model with printA command (look at http://opensees.berkeley.edu/wiki/index ... tA_Command)

Hi all, I am trying to analyze a I beam model with ShellDKGQ element, Here is images of my model generated in another software: - Model overall look: https://ibb.co/kHK7gk - Model with showing nodes (red) and supports (green) and applied forces (pink): https://ibb.co/edVzSQ - input file model.tcl: h...
