Tcl Procedure for Reliability

I have to perform reliability analysis of several different configurations of the same structure. Since the problem is always the same I defined a procedure where the only inputs are R and S. When I call the procedure I get the results once and the second time I get an error. Here is the procedure p...

Fiber results

Is there a way to record results of all the fibers, with their labels.
I have only see a way to export fibers related to certain coordinates in the plane of the section.

K-shaped bracin modeling

I want to simulate the behavior of a k-shaped bracing system, the ones that are used in steel bridges as intermediate diaphragms for lateral loads and for redistribution of vertical loads among the beams. So I want to model a top strutt, a bottom strutt and diagonals with L-shaped elements (ignoring...

Element eccentricity

In my understanding users can define fiber sections with any local coordinate system, opensees will always calculate the centroid of the fiber section and make it coincident with the reference line of the frame element. This way it's impossible to give centroid eccentricity just displacing all the f...

ID in print command output

Hi, when I save the results of a particular node with the print command I get

Node: 1
Coordinates : 0 0 0
Disps: 0 0 0 0 3.14719e-008 0
unbalanced Load: 0 0 0 0 0 0
reaction: 0 0 0.129525 44.5344 -8.1446e-013 0
ID : 1090 -1 -1 -1 1091 -1

could you tell me what ID stands for?

Moment curvature with uncoupled fiber elements

I need to calculate moment curvature of a section where concrete and steel behavior is uncoupled in two different elements. It may look nonsense because I could just add concrete and steel fibers to one section, but is part of a more complicated model that I cannot explain here for reasons of time. ...
