A little bit of intercountry steel trivia

[csd72]

I noticed in the American steel design allowable stress design code that I have that they refer to the old Australian steel code AS1250 as a reference.

Interesting that our old codes still have some influence over here.

Perhaps someone should tell them to reference AS3990; current and still working stress design.

I have never used that, used AS4100 plenty of times but never heard of 3990!

Quoting from the SAI Global website re AS3990;
"Scope
This Standard applies to the design, fabrication, erection, repair and alteration of steelwork associated with boilers and pressure vessels, lifts, cranes, mining equipment, gas and liquid petroleum piping systems, bulk handling equipment and the like, in accordance with the working stress design method.

The Standard does not apply to the following structures and materials:

(a) Road and railway bridges.

(b) Steel elements, other than packers, less than 3 mm thick.

(c) Steel for which the value FY used in design exceeds 450 MPa.

(d) Cold-formed members other than those complying with AS 1163.

Steelwork may be designed to-

(i) the limit states design method of AS 4100; or

(ii) the working stress design method of AS 3990 (this Standard).

NOTE: It is intended that the working stress method will be phased out in Australia as it is phased out internationally"

well working stress is alive and well in the US, i think it will last as long as feet and inches (probably forever)

Personally, and speaking as one who has used both a lot, I can't see why the US engineers would be interested in Australian steel design standards. They can learn a lot about concrete design from us, but steel?

I think it possibly is because that old standard was one of the only other standards that was in pounds and inches.

The code that I am referring to dates back to 1989, but it is the current code in NY city.

AS1250 went metric in the mid 70s, from memory. 1974 rings a bell.

I wouldnt know, I wasnt even in kindergarden at that stage!
