Tilt-Up Wall Design
Tilt-Up Wall Design
(OP)
I have been assigned the task of designing a Tilt-Up Wall. I am familiar with reinforced concrete design, but this is my first time performing a Tilt-Up Wall design. This wall will just be for one side of a building. The rest of the entire building is Pre-Engineered Metal Building. What are the necessary thing to consider? What design aides and/or books are available? Any comments and suggestions are appreciated.

If the wall is insulated then you have two ways to go - the two laminations of concrete work compositely using specialized ties, or, you have one lamination that is the structural concrete portion, taking all the load, and the outer lam is simply a concrete veneer - again tied back to the interior lam but not intended to act compositely.
With openings - you have to ensure you transfer both gravity and lateral forces around the openings.
Also be sure to consider second order effects for thin walls - utilizing cracked or partially cracked section properties in your design.
Some engineers simply design the as-built conditions and leave the actual shop drawing, detailing to others including design checks for the wall panels under lifting conditions (i.e. additional rebar required for lifting stresses).

NZ and UK both have their own industry publications too.
I have this and highly recommend it it you can find it for a reasonable price: Link
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Additionally, remember that some tilt-up walls have architectural reveals that can affect the structural depth of the wall you can use to design the reinforcing.

@spats- The Engineering Tilt-Up book I referenced is from this website. I ask if it is worth purchasing because it's not cheap, but I will buy it if it is very useful for this type of design. The ACI 551 R-92(Reapproved 1997, 2003)TILT-UP CONCRETE STRUCTURES is what I found when I looked on Google. I will continue to look on Google for ACI 551.2R-15 "Design Guide for Tilt-Up Concrete Panels".

The ACI 551.2R-15 publication is available from the ACI store through the link below for $108.50 non member, $66 member, and is highly recommended. I am a member of the ACI 551 Committee. The calculations are quite tedious if done by hand, so if you have more than a few different designs to perform, I would definitely recommend purchasing software. There are several excel-based programs out there that are not very expensive.

Check out the code and you would be able to figure out what its doing.
I still havent finished the wall without any openings completely and it breaks occasionally but this should be a good start.
