Re: modeling of a spring and a damper in parllel

Dears,

I am also facing the same problem.
Is there an effective way to model parallel spring and dashpot model in OpenSees?

Assigning two ZeroLength elements is not working.

Radiation damping, Crad, is not working appropriately in OpenSees.

I am using OpenSees and winkler spring to represent the foundation. Since my ground shaking is not intense, I have chosen 'Foundation condition = 3' which is elastic vertical and horizontal springs. Could you please tell me how OpenSees considers soil radational damping when I choose 'Foundation con...

Re: radiation damping in QzSimple1 material

Dear ZVaghefi, In your previous post, you stated the following idea: "If the spring behavior is elastic, I use elastic material for them and add dashpot elements parallel to vertical springs in order to provide radiation damping. The damping of each dashpot is calculated in such a way as to produce ...

How can I define material and radiation damping of a soil in BNWF model (ShallowFoundationGen command)?

I am using Beam on Winkler Foundation model to represent the foundation. Since my ground shaking is not intense, I have chosen 'Foundation condition = 3' which is elastic vertical and horizontal springs. Could you please tell me how OpenSees considers soil material damping and radational damping whe...

My pushover analysis (2D Frame) is not converging.

Dears, I have modeled a 2D elastic frame in OpenSees. I want to get capacity curve with clear maximum value of force. when I change the value Umax even to unrealistic large value, it gives me a result. It doesn't converge. Could you please help me on how to make it fix. Thank you in advance. Here is...
