Bracing for construction
Bracing for construction
(OP)
I am work on a church that has 90' high walls around the perimeter. The first 22' are 18" thick the rest is 12" thick. The first lift to 22' will be installed and then the structural steel will be installed, then the walls will continue to full height. These walls need to be temporarily braced to handle wind and construction loading. We are considering using wire rope tied anchored to the ground on each side of the wall. Is this a feasable application, or does anyone have any have any knowledge of this type of application.






RE: Bracing for construction
As walls got higher, the buttresses got bigger until they went to a flying buttress.
What will stabilize your wall after it has been built?

RE: Bracing for construction
So you must be the contractor.
You might want to consider the following suggestions.
1. Incorporate as many turns as possible while constructing the wall to give it lateral stability.
2. Talk with structural engineer to find out what aspects are important or critical.
3. Do not remove any bracing until the engineer says the work is complete and stable.
4. Employ an engineer to design your falsework.
RE: Bracing for construction
It IS the usual practice for the structural engineer of record to only considered the stability in the completed structure; temporary bracing for stability during construction is a specialty area (and falls under construction means and methods, which the engineer of record avoids like the plague for liability reasons).
It would be best for you to hire a structural engineer who specializes in temporary bracing during construction.
By the way, ASCE now has a standard, SEI/ASCE 37-02, "Design Loads on Structures During Construction" to aid in the design of bracing.
Good luck!
