Nice line BA... Quasi-religious, and quite poetic. I like it very much.

Not that I have ever heard... As I understand it the problem is too complex to be accurate without knowing more ahead of time.
Why do you need to tell the age of a sample? If you don't know the age, you likely don't know the curing, which likely as not means it does not match what is in the...
I've had a middle of the night, wake up in a cold sweat moment... And it's not even one of my projects! I just need to point out that my list of common rivet sizes has omitted THE most common bridge rivet size; 7/8", AND I've also incorrectly listed 1" as a common size! The 1" diameter rivet...
I would really like to see photos as well, if at all possible...
Cheers,

I was reading through all the posts, with exactly dicksewerrat's thought in mind: These bolts were almost certainly not installed correctly.... IF you can get a nut properly onto the end in this situation you can normally slowly bring the plates together simply by tightening each bolt...
I agree with DSB123; We are a profession that demands self-restraint while working towards professional knowledge and skill enhancement. I believe your best course of action would be to employ/cooperate with a (much) more local engineer experienced in the work you are planning to undertake...
csd72: Not talking about into soil... Did you misunderstand or am I in line to learn something new here?
Looking forward to your reply,

A post in concrete is only like a post in soil in appearance, at least in my opinion. The soil will yield plastically and the loads are reasonably distributed; Your concrete is not going to yield, it will crack. You need to consider the problem elastically. Those nice smooth semi-circular and...
I thought I might chime in with one more point:
Much like our modern steel member tables, you'll find that old rivet tables list a very great number of sizes (something like everything between 1/4 and 1-1/16" in 1/16" increment, however these were not commonly available. The most popular sizes...
In many cases rivets were placed at close spacing for the following reasons (not always obvious to the uninitiated):
1. It was shown in the 1890s that spacing of rivets less than 6" would reduce (and at 4" - Your spacing - nearly always prevent) rust jacking.
2. The designers typically...
Mostly for my own curiosity:
You need to be certain that you really WANT rivets. I've seen an engineer struggle to do a design with rivets in a desire to be "sympathetic" to the existing structure, only to find that no contractor would (or I've sometimes thought even could!) undertake the...
There are a number of these tables available through the Canadian Wood Council. I'm certain the APA will have produced similar ones... I presume you're looking for something in the US?

Sorry about that, I didn't catch that the whole foundation was thought to be this early agg/lime mix... I have seen thin base layers (failing similarly to your's) of say 150 to 300 cement-like material below a spread brick foundation. These are notoriously (in my own mind) difficult to...
You will have future problems if your motar is too stiff. I am not aware of any fundamental chemical reaction occuring to cause deterioration between cement and lime mixes... That doesn't mean there aren't any!
Okay, so you need your new mortar to creep. I would suggest looking into a mix...
