Deflections for Shoring for Historical Brick Wall Facade
Deflections for Shoring for Historical Brick Wall Facade
(OP)
Got a project where I have to design a temporary steel shoring truss for an existing two story brick wall that is to be saved. The existing structure is to be demolished and a new building built that will incorporate the original brick wall facade.
My question is, as it is temporary shoring for a histiorical element, what deflection limitations would you use for the lateral design forces parallel to and orthoginal to the wall?
10' first story height, 8 foot second, with a four foot parapet. The wall will be temporarilly shored for vertical loads in the window openings with wood studs.
L/600?
L/1000?
Something else since it is a Historic Structural element?

When I did the facade shoring for the Cornwall Centre in Regina, I used l/900 as a criteria... there were no guidelines at the time. Minimum would be l/720 as typical for stud supported masonry walls.

If you don't know the mortar, ductility, etc. of the wall then better to play it safe and goe with L/600 or such. But it probably has a higher tolerance for movement than you think.

Perhaps that's why it's "historical".
Then again, could it be the fact that that kind of "Architecture" is "history"?
I need to visit the site next week. If I get a chance, I'll post a picture of the facade - for what it's worth.

Michael.
Timing has a lot to do with the outcome of a rain dance.
