hysteresis in steel 1

Structural
Structural steel used for construction in the USA today is typically ASTM A992. Try a search at the American Institute of Steel Construction (AISC), here is the link to the website
If you are concerned with an existing structure, say built between the early 1960's and the late 1990's, the steel is most likely ASTM A36. There are other grades, both then and now.

Thanks SlideRuleEra,
but not really what i am looking for. The mentioned website is mostly based on hysteresis caused by the combination of plastic deformation or deformation of the structure as a whole.
What i need is information on the hysteresis of steel, for instance in pure elongation or compression. Like the look you get when you compress and unload rubber.
Actually, I need information to show that such deformation in steel is very low (after all: such loop gets bigger if there is more damping, and the damping of steel is low)

I am not sure what you are after. I have a quite detailed lecture called 'The cyclic behaviour of steel elements and connections' which deals with hysteresis with some detail. I do not know if it would have any relevant information for you.
I uploaded it to Rapidshare, the link is below. Please post a message to indicate when you downloaded so I can remove the file

upps!
Sorry deleted the file by mistake. the new link is:

Thanks,
i downloaded the file and it is pretty usefull. It's complicated what i need it for, but basically i want to show that a steel component (an engine support) doesn't get stiffer when you load a component in compression, unload it a little, and then load it again. The client has a graph showing us that it does, we want to show him that this effectc is caused by hysteris in caused in the measuring
