HI everybody.
I have modeled several concrete frames on CSI PERFORM 3D and I want to obtain damage of frames under earthquake motion by Park @ Ang damage index. I did not find any example or guidance for calculation of this damage index (specially for computation of absorbed energy in formulation of the damage index). I would be grateful if everybody could send a link including examples for calculation of the damage index or any guidance.
Best regards
Please find the following paper, in this paper, Prof. Massumi and I have developed the formula for calculation of damage index of Park-Ang by calculating DI for structural members, stories and entire structure, respectively:
Ali Massumi, Kabir Sadeghi, EhsanMoshtagh, Effects of Deviation in Materials’ Strengths on the Lateral Strength and Damage of RC Frames, November 2018, Structural Engineering & Mechanics 68(3):289-297, DOI: 10.12989/sem.2018.68.3.289
If there was not copyright issue, I could send it to you, but it has copyright and try to find it yourself.
I hope it is helpful to you.
All the best.
Hello,

Good work!
