The limit state of damage limitation is attained when the working stress increases to the allowable  stress of materials in any member or when the story drift reaches 1/200 of the story height at any story.

So that means 0.5% in each story if the working stress doesn't reach the allowable stress of materials.

Amir, I thank you very much!
