thanks for your care.It was great of you.

I want to model Triple Friction Pendulum Element in opensees. i have downloaded TPB examples from this link: https://dl.dropboxusercontent.com/u/21442020/TPBDocumentation.rar when I run it on opensees this error comes up: OpenSees > source CheckingTripleFrictionPendulum_1DDynamics_ConstFriction.tcl ...

Hi everybody.i have a very simple 3-d concrete frame.when i perform gravity analysis this message comes up.what is it and how can i solve it?

i use global and local force recorder in order to get element forces after pushover analysis, but the axial force of beams isn't zero.Does any body knows what goes wrong?

Hi.I have the same problem.I have a 7-story concrete frame(2D) and i want to do pushover analysis but whatever i do i face convergence problems . i've tested different analysis parameters and i have changed # of steps and it hasn't worked yet.and i have used FBE and DBE elements and both have conver...

Hi everyone.
i want to model rebar by the use of hystertic material , but unfotunately i have little information about this kind of material.i don't know how to calculate pinchX or another parameters.can you help me and introduce an article about it?

Thanks dear vesna. The target displacement was too large for a 2-story frame and all models converged up to 27cm. Now i have another problem.i modeled the frame using BeamwithHinges,nonlinearBeamcolumn and dispBeamColumn . when i plot their pushover there is a slight diffrence between the first and ...

Hi everybody.I have the same problem. I have a 2D model with fiber section and displacement-based element and I want perform a pushover analysis , but I face this error.Do you know what goes wrong? :oops: OpenSees > source Untitled1.tcl Model Built WARNING: CTestEnergyIncr::test() - failed to conver...
