Damping Ratio in ASCE 7-02

[beamer]

I am currently working through the Gust Effect Factor in ASCE 7-02 and am stuck on the Damping Ratio in section 6.5.8.2. I haven't been able to find a good definition for this or a reference to use. So the question is - Where can I go to find what value I should use for various structures?

Thanks!

Thanks! The 1 to 1.5% for steel is what I was looking for.
