Where are strong backs attached?

• A. At bracing location
• B. At the end of each panel
• C. Along the top edge
• D. Under the slab

Answer: (A)

Strong backs are temporary members used to hold and stabilize a tilt‑up wall panel as it’s raised into position. They must be attached at the bracing locations—the designated points on the panel where bracing is designed to connect—so they can effectively restrain the panel from rotating or bowing and transfer loads into the bracing system. Attaching them at these prescribed points ensures the panel stays square and aligned during hoisting and until permanent connections and shear elements are in place. Placing them at other locations would not provide the correct load path or restraint, which is why bracing locations are the correct attachment points.
