I'm a civil engineer and I mostly stay on that side of this site. I am also a Brazilian living in Brazil, which has its own structural codes, distinct from those in Europe and the US. Given how much of civil engineering is governed by codes, this limits to some extent my capacity to contribute to some questions which are code-specific (and almost exclusively American and European). A two-minute search gave me these examples (there are certainly plenty of others).
- How to interpret this BS 5950:2000 clause for splices in compression members?
- How is biaxial bending considered for reinforced masonry design?
- What is the process for qualifying a weld between structural steel and stainless steel?
- Biaxial flexure of steel I-beams
- Should long-term prestressed girder camber always be upward?
- Thread-locking on AISC Clevises
There are others which while not explicitly code-specific, can only be meaningfully answered by referring to the relevant codes. In such cases, the asker should really tell us where (s)he is from, though that often doesn't happen and so we all chip in with our respective codes. A few examples:
- Is hydrostatic pressure a dead load or a live load?
- What are safe locations for openings in reinforced concrete beams?
- Typical flatness of Portland cement
- First glance: structural integrity of this roof
Now, would it be useful to create tags to be used in such questions, indicating the desired codes (there is already aisc, for example, with a whopping two questions)?
I believe this would be of benefit, since it will allow for faster discovery of questions our experts are most likely to answer. I see it as similar to the "code language" tags at StackOverflow, which are almost mandatory for any question there (not that I believe such an aggressive position would be adequate here).
One possible weakness would be that some experts may limit themselves to questions with the appropriate tag or may at least avoid questions tagged with a code they are not familiar with, when in fact their external view might in fact bring in a relevant insight to the problem, even if only through a comment. However, given the current size of our site, that doesn't concern me. The expert will come in, see no new questions under his/her code-tag but see another question which, while tagged with another code, interests him/her regardless, and goes to take a look out of curiosity/boredom. Should the site grow, I believe the need for such tags only increases, for the same reasons as the "language" tags in Stack Overflow.
If this idea is appreciated, the follow-up question becomes whether the tags should remain general (such as aisc), representing the body/institute responsible for the codes; or if exceptional codes, those most used (such as Eurocode 2 and 3), should be given their own tags. I personally believe the general institute tags would be sufficient.
