Tilt-up Building Expansion Joints

[Boiler106]

Using Expansion Joints in Buildings: Technical Report No. 65 in the southeast USA, do concrete tilt-up buildings with steel joist framing fall under steel buildings?

I tend to think that they do, given that the panels are discrete elements and are not continuous.

Thoughts?

I'd say they're steel buildings.

X3 for steel building. A discrete cross braced wall segment is going to be as stiff as a discrete concrete wall panel. So I think that it comes down to how much expansion and contraction in the deck will occur for the material of construction. And here, the deck is steel.

I’m a little confused by the question since I’m not familiar with the technical report you listed.

I am familiar with tilt-up buildings and normally if a tilt-up warehouse is big enough there will be an expansion joint located based off the precast handbook. The joint between panels maybe 2” vs 3/4” at the expansion joint. The roof will need to be configured to allow for the thermal size changes the building will go through.
