Analysis error

Post by orodzarrin » Fri Oct 25, 2013 9:56 am

these is problem about this commend. i can not find out how to correct it.
pleas help me.

integrator DisplacementControl 5 1 0.1

this is its error :
can't read "nodeTag": no such variable

the number 5 at the first parameter is a joint.

node 5 needs to be a node in the model. does the command "print -node 5" work?

Can you post your node definitions

if that command does not work .. you have no node 5 and thus cannot control the analysis using the displacement at node 5.

may be
do not use rigid Diaphragm in 2d model
it works in 3d model
use equalldof for Rigid Diaphragm
: equalDOF 10 20 1:
why you use ridid link?

I modeled 2D. I tried to use Ridig Diaphram and equalDOF 10 20 1
but it doesn't work.

first
add ; in your Description text
reform

rigidLink beam 4 5; # connect node 3 to node 4 via a rigid link-beam #

use ; # befor your Description text

if didnt correct then:

then reform

There are many mistakes in your code. You need to make the following changes:
1. Commenting: In many places your commenting is being treated as code by the interperter. Please read on how to comment in tcl. Also use notepad++ it will help you with writing your code.
2. EqualDof: in this command you are calling many nodes that you haven't even created. I don't quite understand what you are doing there. I assume you are trying to constraint all the floor nodes? if so here is the code you should use:

equalDOF 4 5 1 2
equalDOF 4 6 1 2
equalDOF 7 8 1 2
equalDOF 7 9 1 2
equalDOF 10 11 1 2
equalDOF 10 12 1 2

3. If you are using equalDOF why are you also using rigidLink? Use one or the other not both
4. the first line is usually: model BasicBuilder -ndm 2 -ndf 3
5. Recorders. You need to review how to define recorders a few of them are incorrect. I have commented out the ones causing problems

So use the code below and it should run but I am not sure about the quality of the results:
