low yield point steel?

[shchao99]

Hi,

Anybody has heard about low yield point steel?(for seismic-resistance)

Can we get this kind steel in any company?

Thanks

In any company I think not yet, but maybe I am wrong. The thing is that some of the A 36 was being labeled so as a marketing convenience, because it also was meeting the specifications for A 50

A steel with such behaviour can have such overstrength that some of the structural schemes devised by the designing team (such strong column / weak beam) can be defeated, in more than having lesser ductility. For these reasons there has appeared demand for controlled yield steels, to which you may be referring to.
