Impact damage to steel bridge beams
Impact damage to steel bridge beams
(OP)
I am analysing a steel-concrete composite bridge that has been impacted by an oversized load, causing large plastic deformation of the lower flange and web.
Could anyone advise whether this plastic deformation will have altered the material properties of the high yield steel beams? With particular reference to young's modulus and ultimate strength.
Thanks.

The ductility of the material may be much less than before.
But those are minor compared to the risk of cracks having started.

I would suggest you review DOT information related to bridge assessment methods and damage to bridge structures. Also, post this question in the forum below below;

The other concern is cracks; I don't think you have any option but to repair those.
