Park-Ang damage index

[julyan]

Hello,

I want to use Park-Ang damage model for evaluation of performance of 2D RC frames.
unfortunately i can't find any link for this purpose .
how can I evaluate this damage index?

Best,

I don't think you will directly get an output of the Park and Ang damage index. Instead, output the parameters you need, such as displacements and curvatures. Also from the force-displacement hysteresis you can calculate the dissipated hyteretic energy. Finally, you can use these parameters to calculate Park and Ang damage index using the formula.

Dear jayghosh,
thanks for your comment. in my search about calculate Park Ang damage index, I found a command but this commend does not work!
