RE: Correcting out of level wood frame structures (was: a frame s horing)

[Subject Prev][Subject Next][Thread Prev][Thread Next]



This approach was used extensively after the Loma Prieta earthquake in the Marina District of San Francisco. Most of the buildings in that area had open parking garages on the ground floor and 3-4 stories of apartments above. The open fronts drifted quite a bit (some as much a s 12”). The jacking procedure was used to return them to plum condition. Of course, this is a highly specialized work that probably few contractors are capable of doing it.

Subject: Correcting out of level wood frame structures (was: a frame shoring)


Changing the subject a little, I'm aware of a new home which was built both out of level and out of plumb by over 2 degrees in some locations. Probes suggested no structural distress of any kind. Foundation settlement was also not an issue. A suggestion arose from another consultant to attempt to correct this via jacking and/or pulling of floor beams and long-term creep of the wood frame. Does anyone have any experience with this?


I was more than a little skeptical of this approach but had been assured that it would work. BTW, this is not a current project. Just a question for interest.
