question about damping factor?

hi

I attended a lecture in which the lecturer recommended for design of steel structures Damping factor is 2 to 3%.
Default value of damping factor is 5% for concrete construction.
What value do you suggest?

Lecturer was right..most of the time we use 2% for steel structures..
