anitha, please.
Can you share the IDA script. I had the same problem?

I appriciate your help.

Did you get it ? it is my problem too.

Re: frame wall connection

equalDOF? The adjacent beam and centerline of the wall are 4 meters apart. Does equalDOF work? The purpose of the stiff beam is 1) to consider the length of the wall and 2) to impose rotations of the wall to adjacent beams. equalDOF, in this case, imposes the rotations of the centerline of wall to ...

Re: double curvature test

I have read the report "Shear-Flexure Interaction Modeling for Reinforced Concrete Structural Walls and Columns under Reversed Cyclic Loading". In this report, it is mentioned that analytical models of column specimens were generated in OpenSees using the SFI-MVLEM model elements. Three of the four...

Re: shear wall cyclic behaviour

Hi everyone, I am trying to model a shear wall with SFI-MVLEM. I used Menegotto&Pinto constitutive model for steel and Chang&Mander for concrete. I calculated all the concrete parameters following Chang&Mander formulas, except the values of xcrnu and xcrnc (see the code later). The model seems to w...

Re: SFI-MVLEM shear wall modelling

Hi, I currently am working on a research on the validation of SFI-MVLEM analytical modelling on a variety of shear wall specimens, including non rectangular (barbel and flange-shaped) ones. I am using the example file Example1. SFI_MVLEM (http://opensees.berkeley.edu/wiki/index ... r_RC_Walls) as m...

Re: Error using "nDMaterial FAReinforcedConcretePlaneStress"

these materials cause problems .. i have some newer materials for modeling walls .. you might even try forgetting the beam elements with these .. here is some code copied from an example put together by Dr. Petrone # Concrete # Parameters for the new concrete model set E [expr 36900e6*$Pa] ;#elasti...

The quickest way of debugging your tcl file is to add puts commands in several lines to see until which point it proceeds fine. Also it is needed to run opensees from the command prompt to avoid sudden closing of the window

Re: modelong of rigid diaphragm in 2d steel frame

Yes you need to use transformation, penalty or Lagrange multipliers for mulit-dof constraints (i.e. constraints that related different DOF to each other) Thanks for your time but I faced with a Problem when I run my model , It did not give me a results, my results of elements and nodes will be zero...

Dear all

I want to use "rigid link" command considering beam attached to wall. However, opensees say that "constraint matrix not identity" and I could't get the analysis. Please teach me how to solve the problem or another way to analyze.

Hi,

I have the same problem with my model. It will not converge, I was wondering what was the problem with your model, maybe I can have a look at mine as well.

Thanks,
