Re: Singular Matrix Error - for Shearwall Pushover Analysis

Dear mhscott Thank you for your advice. I found that I have a modeling issue. I am not sure how to attach the coupling beam element to the SFI-MVLEM (shear walls elements). I tried to do this using the following script: 1. Create nodes on the edge of the walls 2. Create rigid link beam elements from...

Re: Singular Matrix Error - for Shearwall Pushover Analysis

Hi SunaiKim, I am working in a 25 - Dual System (Coupled Walls - Moment Frame) with shear-flexure interaction elements (SFI_MVLEM) model. For the moment frame, I have used beamcolumn elements modeled with plastic hinges at the ends of the beams using uniaxial ModIMKPeakOriented materials. For the wa...

Concrete Stress Strain Curve

Hi,
Has someone an example on how to generate the hysteretic stress–strain curve for ConcreteCM uniaxialMaterial.

Re: SFI MVLEM recorder

Thanks Mr. Michael H. Scott, Ph.D.

It was the issue. I fix that in my script and now it works well.

Best regards,

SFI MVLEM recorder

Hello, I am a new learner of OpenSees and have started learning it through its Python version. My question is about generating outputs for a SFI_MVLEM strain and stress. I am currently working through the example SFI MVLEM - Cyclic Shear-Flexure Interaction Model for RC Walls, which is available at ...
