Thanx. I solved it!

hi, I have a model about selfcentering connection in steel frame. When I run transient analysis with elastic beam, column, tendons and nonlinear gap opening & energy dissipator, it worked.. but when I change elastic beam to nonlinear beam element ( Dispbeam, beamwithHingemodel etc) it didn't wor...

Hi dear everyone. I have questions about recorder command for outputting node and element force and displacement. However, when I see the values, the end parts of value is not coming.. For example, I did cycle loading analysis by using displacement control and Final value of displacement is 219. I c...

Hi all, I'm trying to analysis of cycle loading and my model is related to the selfcentering connection which means there's no residual deformation by using the elastic force of strands across the beam and energy dissipator installed between beam flange and column flange. First, I'm done exterior co...

I appreciate your help. I can understand your helpful answer a little..But it is remained to wonder. I think the time and load factor entered pattern load relates to Domain object. so i have some questions. 1) In the case of Static analysis, it is no need to consider the time. why I enter the time s...

hi. Dear fmk, every I have just question about lateral load related to static push over ad cycling loading. I saw that there were a lot of example about assigning lateral load. I have had a question why did the lateral load assign when I used displacement control.. fortunately, I understand a little...

i don't know the problem of connecting node..
what is problem nodes at ends of the 2 elements of mine?

Hello. i'am opensees first users.. i got this error when gravity analysis.. ↓ WARNING BandGenLinLapackSolver::solve() -LAPACK routine returned 2 WARNING NewtonRaphson::solveCurrentStep() -the LinearSysOfEqn failed in solve() StaticAnalysis::analyze() - the Algorithm failed at iteration: 0 with domai...
