Has anyone come across procedures or guidance on how to replace construction materials (concrete, steel …) specified to US standards (ACI, ASCE, ASTM …) with European materials so it can easily understood and produced by European suppliers?
Dear Smail,
please have a look at the converter in the attached link. The others may also be helpful to you.
Good luck.

Gerhard,
Thank you for your prompt response. I am looking for a logic follow chart or written procedures that can help designers to specify European replacement material to the specified US materials with particular interest in civil engineering concrete and steel for structures.
thank you again

I would not convert specifications in one standard to another for strength and durability. I will suggest you use the local specs and make allowance for climate change. For example, a cover to reinforced concrete member may be necessary to adjust for durability due to current climate change impact. Europe is no where near America. Avoid making things complicated.
Hi Albert
Thank you ... it is much appreciated. Some structures here in the UK are designed to US Standards including materials are specified to ASTMs but materials in accordance with ASTM is not always available so we do have to substitute it with European materials and this create issues with the regulators.

Dear Smail
Some countries in the Asia-Pacific region are experiencing similar problems following their adoption of the Eurocodes. In this case, they have problems sourcing materials that conform to the EN product standards that are given as normative references within the respective Eurocode. I authored a paper for ICE recently, that may be of interest, which can be downloaded from here https://t.co/4D0CoZ6HkI
For your case, I think you will need to compare the statistical properties of the materials required by the ASTM and see if these are similar (or worse) to those required by the EN product standards. For structural steel, although not mandated in EN 10025-1, etc. the statistical properties assumed for the calibration of Eurocode 3 are given in the link to my paper (see above). Whilst it is my understanding that the most recent study for North American standards is presented in the following:
Bartlett, R.M.; Dexter, R.J.; Graeser, M.D.; Jelinek, J.J.; Schmidt, B.J. and Galambos: ‘Updating Standard Shape Material Properties Database for Design and Reliability’, Engineering Journal, AISC, Vol. 40, No. 1, pp. 2–14, 2003.
For structural concrete, I would suggest that comparisons are made between EN 206 and the following:
ACI 214R-02 Evaluation of Strength Test Results of Concrete, American Concrete Institute, Michigan, ACI, 2002
I hope this helps.

Hi Stephen
Thank you for the detailed response. Your paper is a very interesting reading and enlightenment to people in relation to the issue confronted by designers, suppliers and contractors following the adoption of new design codes. Thank you again for your valuable advice in how to deal with such situation.
Best regards
Smail
Hi Smail
A good reference which allows the comparison of steel types is the Key to Steel: http://www.keytosteel.com/en/

Hi Christoph,
Excellent suggestion. I will definitely explore it and see if it would help in my case.
many thanks
