Eurocode - Steel Design

[ash060]

Working on a project overseas, and was told that they used the British standard in this location. I did a little research and saw that the Eurocode is the current one in force (not sure if this is correct). Is anyone familiar with those codes regarding steel and concrete design? Do they greatly differ from the American codes? Does anyone know of a good textbook that does an overview of their design methodology?

Which codes would I need to get in order to make sure that I have everything covered?

Thanks

Whereabouts are you? And what are you working on?

Based on my experience ACI and Eurocodes use different methods to gain the same result however the terms/equations differ. If you're working mainly in structural engineering it will be BS EN 1992 (Eurocode 2) you are looking for, this gives all general rules for concrete structural design, fire resistance, bridges, buildings. Eurocode 0 is handy for design values/factors etc and Eurocode 7 provides instructions for geotechnical design. There is something called the Blue Book steel designers manual which we also reference for steel design in the UK. Be sure to refernece any UK national annexes to the Eurocodes if you are working in the UK as the factors/rules can deviate from those suggested oftentimes.

These are the main ones I can think of but they should put you in good stead. Have a cross reference with the ACI and you'll see there's not much difference.

There's also a good book called "Reinforced Concrete Design to Eurocode 2" by Mosley, Bungey and Hulse which I reference regularly. 6th edition is most up to date I think.

Overseas = where? Europe (mainland), or the UK?

there' s a good EC forum, although it doesn't seem to have many active members.

there's also a subforum (or thread) of good reference books, worth giving it a look as there are three very good steel eurocode books, you'll find 'em there. don't know about concrete.

Middle East is where the project is located. Some information that I found suggest that the area where the project is references the American I-Codes, but I am hearing from an engineer over there that they use British Standards for their steel. I am not sure if they design with American codes using British Shapes, or design with old British Standards with British Shapes, or use the Eurocode

I suggest if you can get away wiht it use the British standard.
For steel desing you woud need access to
BS EN 1990, 1991, 1993, inclusing all the relevant sub documents i.e. 1991 has 7 parts I think, 1993 has about 11, plus all the national annexes (not sure how that works for projects outside europe) a raft of NCCI (non contradictory complimentary information) documents, access to steel biz web site, how to guides,

Good luck.

Hi

I am based in the UK and I use, or am converting from the old standards to the eurocodes.

Depending in which country you work in, you will need two codes: the Eurocode and the National Annex. The Annex is the most important part and is local to the country you are working in. For steel you will require BS EN 1993-1-1-1:2005 and NA to BS EN 1993-1-1-1:2005. The BS EN is the same for every country in Europe, only the NA is different. In the UK, we have to buy our standards and they are very expensive. Check out '

archive dot org slash details slash texts'. Type in British Standards and you will find them all.

There is a Eurocode formum

http://www.designtoeurocodes.com/forums/forum.php

which I have found helpful.

The Eurocode has a theory-based approach to design and the code states that you may use any theory provided it is valid and this includes other design-codes. Therefore, it may be permitted to use an American-code provided it fits the Eurocode criteria - whatever that is - Ultimate Limit Design I assume.

Hope that helps

I would shy away from using other national codes, they may and be highly unlikely to be satisfactory to be compliant. I think where cve is getting confused is that the eurocode sets out principal clauses which must be satisfied. It then states several sub clauses which may be followed and will comply with and satisfy the principle. Your can use other methods, such as first principles etc as long as they comply with all the fundamentals of the eurocode and you can demonstrate in the location and for the structure concerned that you get the same reliability. I would suggest it would be very time consuming and difficult to prove you are getting the same with another national code. Especially as material properties and detailing rules assumed within said codes will be different.
On a general note the eurocode s are not 'design guides' like a lot of other codes and like the British standards. To be honest they may as well sometimes just print a one liner that you should satisfy the structure can carry the applied loads witan suitable factor of safety and let you sort it out.

Does the substitution of the eurocode with another code apply to other British Standards. For example: I was looking for a eurocode method on the design of a 2-way-spanning concrete-slab and was directed by book (Reinforced Concrete design to Eurocode 2:Mosleyage 225) towards using BS8110 in place of EC2. The given example uses the code in its entirety and makes no reference to the eurocode.

Am I wrong in assuming that another code may be used as replacement? The book does imply it should be acceptable (attached) but was not definite.

Sorry if I misled anyone.

Regards

I am not avle to view your table but i assume it is the table that provides a factor to apply depending on the span length in either direction. this is acceptable as it is based on an elastic analysis of a two way slab. it is just an analysis carried out and tabulated to save you doing it every time. so it would actually be code independant.

Just looked and yes it is so you can use it.
