Anchoring to a wall requires the formation of a complete load path

Anchor to wall: Use Stud Finder Hold still against wall to calibrate before moving Partition wall Steel Frame

Steel Framed Structure Restraining strap attached to the refrigerator with an adhesive and to the structure with a heavy gauge metal screw. The partition wall behind the refrigerator is wall board all the way across the room. The partition wall is attached on top to a steel beam. Initially the partition wall was thought to be a fire wall because stairs were behind this wall. From attic could see that the wall was not a firewall.

Restraining book shelves Make overheads of details in Section C of the Nonstructural Protection Guide. Use to discuss the installation recommendations, common attachment problems, types of anchors that might be needed, etc.

Masonry Partition Wall Issues: capacity of the wall

Special retrofit anchors may be needed Drilled-in anchors Mechanical Adhesive (poor quality concrete, masonry, brick) Common installation errors Failure to follow manufacturer’s installation instructions Inadequate hardware substitutions

Installing Mechanical Anchors Concrete must be in good shape Minimum edge distance must be maintained Use required torque and calibrated torque wrench (Photo: FEMA Seismic Retrofit Training to Building Contractors and Inspectors)

Must Carefully Clean the Hole (Photo: FEMA Seismic Retrofit Training to Building Contractors and Inspectors)

Must Blow Out the Fines (Photo: FEMA Seismic Retrofit Training to Building Contractors and Inspectors)

Need proper edge distance Improper Edge Distance in Concrete (Photo: FEMA Seismic Retrofit Trainingto Building Contractors and Inspectors)
