Re: Extra lines of data in globalForce recorder
Yes I have the wipe command at the top and end of the script and it is still happening. It is strange that it only happens for certain elements. Any other ideas what could be going wrong?

Re: Extra lines of data in globalForce recorder
Thanks for getting back to me. Here is my script. It only happens for the elements near the centre of the span. #------------------------------------------------------------------------------------------------------------------------------------------------------ # GRAVITY ANALYSIS #----------------...

Extra lines of data in globalForce recorder
Hi there, I have a 3 span bridge and I apply a gravity load to the entire deck. I use globalforce recorders to record the forces in the deck. In the centre of the mid span however I get extra lines of data at the end of my gravity analysis for some reason. I have pasted the data in one of my recorde...

Re: ultimate curvature
Hi everyone, I too am trying to find the ultimate curvature. However my the moment does not seem to reduce at any point, it just seems to keep increasing with curvature? I'm wondering is there a problem with my code? Maybe the way I define my materials? If you could take a look I would really apprec...

Moment Curvature Analysis-Fail to converge
Hi there, I am trying to do a moment curvature analysis of a RC circular cross section but it is failing to converge. I was wondering if you could tell me what I am doing wrong? I have copied my code below(It is based on the mom-curv example on the website). Thanks # Define model builder # ---------...

Force Recorder Sign Convention
Hi, I have a simply supported beam with a UDL along the full length so it has a sagging moment all along the beam. However when I use the globalForce Recorder for one of the elements along the beam I get My to have an opposite sign at either end of the element? I am confused as I would have thought ...

Corotaional Transformation Command
Hi, I have a model of a simply supported beam with a rectangular fiber cross section. When I use the linear transformation command the bending moment I get at centre span is correct but when I use the Corotational transformation command the bending moment is far to small (around 2Nm). I was just won...

Re: HELP:nonlinbeamcolumn element recorder
Thanks very much. Am I right in thinking that developing a shear force-deformation relationship for my section which consists of a slab supported by 5 U-Beams would be a very complex task? If I only require the shears at the ends of each element would I be able to get them from the element force rec...

Re: HELP:nonlinbeamcolumn element recorder
I tried defining my section in that order but I am still getting zeros for the shear. It is a bridge deck section consisting of a concrete slab with 5 U-beams. I don't think there is a problem with my section however as I used the same section in a simple model fully fixed at both ends and the shear...

Re: HELP:nonlinbeamcolumn element recorder
Thanks I did that and I am now getting my shear forces to be zero. Any idea what might be wrong? I have copied and pasted the relevent parts of my code.

Re: HELP:nonlinbeamcolumn element recorder
Hi,
I am trying to use the force recorder to find the shear forces in a section but it is only outputting 4 columns which are P Mx My T. How did you get an output with Vx and Vy also?
Thanks very much
Kind regards
Mairead

Node recorder for eigenvectors
Hi there,
I am trying to use the node recorder to record eigenvectors but it won't work. It is giving the error "datatostore nodenot recognized". It has worked for me before so I was wondering has the node recorder changed on the new version of opensees?
Thanks very much.

Re: Download tcl/tk 8.5.9
Thanks but I can only find version 8.5.10 on that website which won't work with the current version of opensees.
