bilinear model

Hi everyone, I want to extract an elastic-perfectly plastic model (EPP) from a BoucWen model. Firstly, Are the following values for BoucWen model parameters suitable to convert BoucWen model to EPP model? Secondly, what values should be considered for "$Ao" and "$deltaA" paramete...

Soil structure interaction

Hi everyone,

Is there anyone who modeled SDOF system considering soil structure interaction and using non dimensional parameters such as the non-dimensional frequency as an index for the structure-to-soil stiffness ratio?

Thanks

Assigning damping

Hi everyone I modeled a 2DOF system with two zerolength elements and three nodes. Each element has a specific damping value. In order to assign rayleigh damping to each element, I used region command. I analyzed the system under earthquake excitation. But I encountered a problem. The rayleigh dampin...
