For steel members 1-2 times the section depth is a reasonable assumption for the plastic hinge length. There are empirical formulas to approximate the plastic hinge length of RC members. See articles written by Paulay and Priestley. Dr. Scott, do you have any reference that points out more clearly ...

Hello. I have trouble to get the damage recording using the Fatigue material with a truss element. When I look the output file for the fatigue damage its empty, but the other files (axial force & deformation) are fine. Before I wrote this code, I used the code written by Patxi Uriz. He used the ...

Hi, I want to know if there is a way to calculate the cumulative plastic ductility of an element with Steel02 material for a cyclic uniaxial test. I'm asking this because I don't know if its correct to consider in the whole test a yield deformation equal to Py/K (Py: yield strength, K: stiffness) to...

I have a conceptual question. The Bauschinger Effect in steel is derived from isotropic hardening, kinematic hardening, or both? Is sufficient to represent a steel section with the isotropic hardening properties available in Steel02 Material? My final purpose is to model a Buckling Restrained Brace,...

I was reading about the Hardening Material, and the references are nowhere. I want to know where are the references to this material, so I can better understand its behavior. Thanks!

Hi, I want to know if someone had take in account the inelastic shear deformation of a column-beam element, especifically to model shear links in excentrically braced frames using opensees. I'm a newbie, so I'm looking for the relative advantages of this code with other code called RUAUMOKO, which i...
