Response Modification Factor

[bobbywvu]

Hello,
I want to read about response modification factor, significance and factors affecting R value. I need to know how R value varies with material. I am basically looking for composite materials. Can anybody suggest me some books/websites.

Thanks a lot,

Response Modification factor depends on the system's ability to dissipate energy and depends greatly on ductility or inelastic behavior. It is also affected by the system overstrength factor.

Thank you for your reply. As I mentioned, I am looking for response modification factor for a system built using FRP composite materials but composites are not ductile instead it can absorb some energy before failure. So I thought I should read some background on how I can connect energy absorption of a material to R value.
