There is n't anybody to help me?

Hi, I want to model a concrete beam with fiber.The length of the beam is 2 m and has got 2 pint load in each (2/3) 0.6667 m. I used 2 bars at the bottom of beam its diameter is 20 mm I think my analysis didn't correct. 1- how can I use fiber in concrete? 2- how can I get Moment-Curvature diagram? 3-...

Please help me.

thank you very much.it works

could you run all of the above codes by yourself and check the problem please?
I need ur help.

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

it is in the model.
no it doesn't work.

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.

what's the meaning of extension exactly ?i write it in Text Document.
about the directory i am sure that is correct, i put in opensees program folder.

pleas help me about this matter

analysis shows this error : can't read "nodeTag": no such variable what is this error? which tag dose it mean? there is just "integrator displacement" tag but I don't think so it related to this tag! this is my analysis: constraints Transformation numberer RCM system BandGeneral test NormDispIncr 1....
