Re: Damage Index in fatigueMaterial
Thank you very much fmk for your help. Sorry for late acknowledgement. I tried damage recorder with various combination to record DI for different fibers of many non-linear beam column element in my model. One thing I want to know is whether any code or command is available to record maximum damage ...

Damage Index in fatigueMaterial
Hi all, I am working on SCBF with braces modeled with steel02 material wrapped with fatigueMaterial. I would like to know that is there any way to capture final damage indices (DI) of the brace elements during analysis run? This variable is used in the source code of fatigueMaterial. Also is there a...

Damage Index/ Cycle counting in fatigueMaterial
Hi all, Let me post my query in another way. Is there any way by which I can record final damage indices (DI) of elements wrapped with fatigueMaterial? This variable I suppose is used in the source code of fatigueMaterial. Always appreciate your informative replies. Thanks and regards, Ankit Prakash...

Plastic Hinge Monitoring
Hi all, I'm working on non-linear analysis of SCBF structures. I am a bit confused regarding checking for plastic hinge formation and rotation at plastic hinge after reading some of the earlier posts. I have used nonlinearBeamColumn elements with 3 integration points with fiber section for modelling...

Cycle counting in fatigueMaterial
Dear all,
Can anybody please guide me about the method of counting no. of equivalent complete cycles experienced by an element of material wrapped with fatigueMaterial (Uriz)?
Thanks and regards,
Ankit Prakash

SCBF Example: rigid truss elements for beams
Dear all, I have one question about the SCBF 2D example script available on the website. The model includes "rigid truss elements to assure that the beam nodes move horizontally together" provided between the beam nodes at shear tabs. I want to know the reasoning/principle behind this, why...

About SCBF 2D example
Dear Vesna, For the given SCBF 2D example, can you please share the calculation for nodal masses (horizontal & vertical) or any reference for the same? I have some doubt about it. The gravity load given in the file is 0.11238 kips/in. whereas nodal horizontal mass is only 2.513 kips. If we assum...

Re: calibration low cycle fatigue uriz
Perhaps, it is true that the SCBF example posted on the site does not work for drifts higher than 1% or so. Since this problem is faced by many OpenSees users including myself, I request Vesna/fmk sirs to kindly share any remedy if they have. It would be quite useful for many researchers/scholars wh...

Re: SCBF 2D Analysis - Solver Problem
Dear fmk, Thank you very much for your prompt reply. I've tried all three options suggested but I'm getting the same error message. May be the problem is somewhere else in the script which I'll try to find out. Meanwhile, I've created another script for 3-storey single bay SCBF frame using Vesna's s...
