yes, me to!

ok, at first sight it seems ok. but if you look the recordere element, for istance @FORZEtraviY_1112.out, you can see that all the force are 0!

hi silvia! 1) i tried with a simple 8-nodes moldel without torsional stiffness --> OK (and before i have problem also with simple 8-nodes moldel for beam in y direction). 2) after i eliminated torsional stiffness in my model: i removed section aggregator command ---> the result from eigen analysis i...

hi silvia!

probably i found the error: it's linked with torsional stiffness. i make a mistake when i place it into the model. now i'll try with default torsional stiffness and i hope it's all ok. after i'll say to you if it's ok.

no, i didn't still look at BuildingTcl.

thx!

hear you soon

hi silvia thx for your fast reply! 1- really i don't see difference from examples manual's scipts ( i compare my model with the exemple 7). 2- for the eigen analysis, i think that there are no problem: i have a 6 floor building, and the periods are: T1=1.1383124975173782 T2=0.8036370348873173 T3=0.7...

hi all! i'm performing a dynamic analysis on a 3d rc frame building (column in z-direction and beam in x direction and in y direction). i've a question: when i do the dynamic analysis opensees says to me: " WARNING - ForceBeamColumn3d::update - failed to get compatible element forces & defo...

i found the error: fix

thx

hi silvia. thank you very much for the fast reply. ok, eigenvalues are not right - eigenvalues negative!?!? impossible? - (i found it before appling gravity) and are opensees says to me: " -1.777160e-010 -4.939411e-011 1.647267e-011 5.835856e-010 1.024824e-009 1.485272e+000" domain error: ...

hi all! i built a rc frame 3d building (6 storeys) with fiber section. now i apply gravity load, but opensees does error: " WARNING: CTestEnergyIncr::test() - failed to converge after: 10 iterations NewtnRaphson::solveCurrentStep() -the ConvergenceTest object failed in test() StaticAnalysis::an...

ok

thx!!!

hi all i do a 3d model. when i run it opensees says to me: "Domain::addNode - node with tag 17already exists in model WARNING failed to add node to the domain node: 17" but before i don't built another node with tag numbered 17!!! if i change number (for example 107) i have no problem. and...

yes.

thank you very much for the fast reply

hi all i cannot use the section agregator command: opensees says to me: "ForceBeamColumn3d::ForceBeamColumn3d -- no torsion detected in sections, continuing with element torsional stiffness GJ/L = 1e+010" i cannot understand what's the problem... could someone help me! Here down the script...
