I doubt that the vault will settle more than the soil, as it bears on a lower, possibly stronger strata that was probably pre-loaded by the overlying soil that was removed for the vault. However, I guess if the applied load on the vault is very high that is a possibility. It's worth it to try...
We usually neglect any sliding resistance of the soil, as it could be eroded or settled and not in contact.
I admit I only spent approximately 90 seconds thinking about this.
The design of the structural slab was modified during construction from a beam-shape to a flat slab only, and this change is the source of the problems with ponding, cracking, etc. This was the original cause. Now, 40 years later, the proximal cause of the collapse (or, at least, the deaths due...
This situation IS different from Googling symptoms. I cannot purchase prescription medicines or perform surgery to treat myself (though I can buy supplements to attempt to treat or choose to ignore the symptoms based on what Dr Google says).
And, "Google" in this sense is just a general term...
I don't see how it is possible. Everything I design is bespoke -- a one-off design.
And I didn't say I was considering the gig. What I am asking is whether it is ethical to assist AI in modeling the practice of engineering.
As I get older, I am starting to think that the person certifying such a structure should be about 40 years old, so that there is a reasonable likelihood that the person will still be alive when the problem that design standards were created for comes to pass. A 70-yo guy might reasonably be...
I have a LinkedIn account but only log in about twice a year. In searching for info about another person, a link to the person's LinkedIn profile required me to log in. While I was there, I noticed the latest PM to me from someone who did not provide his last name, only the initial "A.". He was...
I think it goes without saying that the provision of the NSPE code quoted below would apply to any governmental agency RELYING ON the engineer's work that was presented to the governmental agency. The engineer and his client should have stated, "Mr Smithson, here, owns 55 acres in this basin...

They're all about deepening the harbor for bigger and bigger ships, but not about protecting the bridge...
As the ship channel is linear for about 12 miles (maybe 8 miles upstream in the harbor and 4 miles downstream on the ocean side), it seems that a line of many smaller dolphins could have been placed on the approach to the bridge supports. I know this means that ships have to go upstream and make...
For some reason (election, anyone?), Biden decided to say that the TAXPAYERS were going to foot the bill for the new bridge. (He said "Federal government", but he meant "taxpayers".) I would hope that he means the cost after the owners of the Dali and their insurers pay to their limits.
I regret even bringing this up, but could the power failure be due to a cyber attack? Hope the authorities are recovering and analyzing the software logs.
Some basic information: "The Francis Scott Key Bridge, known originally as the Outer Harbor Crossing until it was renamed in 1976, while still under construction, or simply as the Key Bridge or Beltway Bridge, was a steel arch continuous through truss bridge spanning the lower Patapsco River and...
