oh yes i got it!! thanks alot

oh yes 7 colums! tnx i have checked in a simple beam with concentreted force at the midspan. following : wipe #--set up------------ file mkdir SB; model basic -ndm 2 -ndf 3; #y #| #2----------3----------4----> x #|slave| #1 #|master| # Define nodes # x y node 1 0.0 0.0 node 2 100.0 0.0 node 3 50.0 0...

hello, i want to record element localforces so i use this : ( my model is 2D) recorder Element -file ele1local.out -time -ele 1 localForce it records 6 column for each step that i don't know what are ther refer to?! in the manual there is : localForce 2D, 3dof: Fx Fy Mz 3D, 6dof: Fx Fy Fz Mx My Mz m...

oh, thanks very much.
i sent file to you.

for reducing time of analysis i changed steps to 10000steps as following : # Set up analysis parameters constraints Transformation ; numberer RCM ; system BandGeneral ; test EnergyIncr 1e-6 25 0 ; algorithm Newton ; set controlnode 3 set loaddirection 1 set currentDisp 0.0 foreach Dincr { 48e-4 -96e...

Dear professor vesna I have convergance problem again in my code! the problem come over when i choose big displacement for my cycle loop. in displacements shorter than 28cm there is no error but when i define 30cm or bigger one it desn't turn back when loading direction changes, as it was in my prev...

would you please give me an example in a steel frame?
I have problem in defining beam sections and column sections!
if i define one section for both, how the opensees model them, i mean about local coordinates!

hi,
If anybody have an idea about rigid offset in braces? as in Uriz researchs it should be 1/10 of brace length?? it's too big, isn't it?
please help me.
thanks

Hi, i have a frame that i want to define fiber section (as patch quads) for elements.(xy plane) , i mean for example in IPE20 for column we could have 2 different way : (just imagine you are looking at section from above in xz plane) 1) I shape ---- | ---- or 2) H shape |---| How should i define pat...

Hello,
Would you please help me about ground motion? how can i put excitation?
thanks

Really!!! would you please send me your changed code?
Maybe i got wrong?
Maybe there is a problem with my pc!!?I'm confused
thanks

I have tried this(equalDOF 7 71 1 2 and equalDOF 7 72 1 2) . but when i checked nodes displacements it was strange!! node 7 and 71 had same displacement but node 72 had different!! about 10 times more than 7 and 71 displacement!!??

Hi,
I have the same problem!!! My windows is vista.
I can't download it. I got the message : File not found error 404!
Anybody help?
thanks

Dear vesna,
Sketching here is difficult, so I have send tcl file for you.
thanks.

yes, the coordinates are same in all nodes. I equalDOF them in Dx, Dy. in fact this node are part of my code in the end of my brace. nodes 71 and 72 are rotating as a friction damper. and i want to pin the brace to them. in otherwords, brace is connecting pinned to 2 element that are connecting fric...
