I looked at a repair job that involved rusted foundation straps in a crawl space. The straps were embeded in the concrete foundation and attached about three feet up on various joists and beams. On top of the concrete was wet sand. The straps had no chance. They rusted in half at grade.
I’m trying to figure out the best fix.
We are ground zero for hurricanes and earthquakes.
Anchor bolts into the foundation and bolt a new section onto the existing unrusted strap?

I might either call the tech people at Simpson for suggestions or have an engineer come up with a solution.
Earthquakes in Charleston????

Excellence is its own reward!
In 1886 Charleston had the biggest quake ever, east of the Mississippi. We are still digging out!!! We get ten to fifteen small quakes each year. One day we're gonna get the big one.Constructing in metric...

i have heard that about chareston as well, when i moved to the east coast from the west coast and i started talking to people about welding certifications i told them about the certs i have expecting them to gush like they do in california and they look at me like i am from another planet!, they've never even heard of it.
finally i ran into a certified welding inspector on a job and asked him about it, was told that they are beginning to implement some of the earthquake requirements on the east coast that they have in the west coast , at least in the major urban areas and charleston SC is leading the way.
previous poster is absolutely correct in contacting simpson about problem, they are the experts, and will have a retrofit bracket that you can mount into side of stem wall with rotohammer and redheads that will do the trick for you!
Ask Ms Shredder, she built a castle in that sand, and she gots the smarts to engineer the fix for that area.

No definitive answer, but Simpson does make all sorts of retro fit stuff for seismic anchoring, . A tour of their site or some of their catalogues should show something.
Combination of bolts, epoxies, straps etc.
My guess is that any local steel fab shop could bend up some L brackets that could rest the short leg on top of the plate then anchor bolt the long leg into the foundation wall.
OR
Bend a 90 degree twist in flat stock and thru bolt it to the joist and anchor it to the wall
