Galvanized steel elastic modulus
Galvanized steel elastic modulus
(OP)
Hi guys,
I was just wondering what effects galvanising has on the elastic modulus of 'ordinary' steel? I assume it increases but by how much?
I need to know this as I'm trying to calculate a deflection for a galvanized steel beam.
Thanks!

RE: Galvanized steel elastic modulus
I have to confess I have never thought about this, but I would have guessed it is unaffected. Galvanization is supperficial, is it not? affecting only to the outer layer of a section. The heat from the galvanization bath is too low to change the properties of the steel (in most cases for most types of steel), and it would only affect strength or toughness, not elastic modulus.
When designing galvanized elements I have always assumed (maybe incorrectly) the same elastic modulus as for black steel.
I would be curious to hear other people's opinion.

Good question, I'll see what I can shake out.

I would however consider the additional self weight.

Timing has a lot to do with the outcome of a rain dance.

Or you have too much time on your hands.
Don't forget - there are also mill tolerances with steel. I've never met anyone who took into account the possible variations in dimensions.

The thread has obviously been trimmed due to someone redflagging some comments. I think the comments were in the sarcastic vein about your contribution, which was judged to be repetitive.

Arguing with an engineer is like wrestling with a pig in mud. After a while you realize that they like it

RE is half right, I wasn't pretending to be a client.

As for bridgebuster's comment: "I've never met anyone who took into account the possible variations in dimensions." Don't read chapter C of AISC 13th it'll make you sick.

Question: What is the practice if one is following AISC? Is a designer expected to compute multiple values of S? In looking at the spec, it looks like it could be argued both ways. A few months ago, I attended a short AISC seminar that didn't make any reference to different values of S.
