Title: Enhancing Structural Integrity: The Atir Strap, Bonded Beam, and the Significance of the “72 Install” Specification

In modern construction and seismic retrofitting, the synergy between tension-tie systems and continuous load paths is critical. Among the most reliable methods for connecting roof structures to wall framing is the use of the Atir Strap (often a proprietary or generic term for a heavy-duty galvanized steel tension tie) in conjunction with a bonded beam. When specifications call for a “72 Install,” they are referencing a specific, high-capacity anchoring protocol that demands attention to detail, precise fastening schedules, and adherence to engineered load values.

Step 2: Mark the 72-Inch Fastening Zone

Measure 36 inches to the left and 36 inches to the right of the beam-to-post centerline (total 72 inches). Alternatively, the strap itself may be 72 inches long. Mark a reference line along the beam’s side where the strap will be seated.

Fastener Pattern (Typical for a 24-inch long ATIR strap):

• The strap has 8 rows of holes per inch of length. A 24" strap provides roughly 192 holes, but not all are used. For a 72-fastener install, you’ll load every third hole in a staggered pattern.
• Spacing: Fasteners every 1 inch along the length, in 3 staggered rows. That yields 24 fasteners per row x 3 rows = 72.

Step-by-Step Procedure for an Atir Strap & Beam 72 Install

Phase 1: Beam Preparation & Bonding

• Material: Use a minimum 3-1/2” thick engineered beam (or built-up 2x6s or 2x8s). Apply a high-strength epoxy or polyurethane structural adhesive (e.g., Simpson Strong-Tie® SET-XP or Loctite PL Premium Max) between each ply.
• Clamping: Clamp or nail the plies together every 12” O.C. with 16d nails or screws.
• Curing: Allow 72 hours undisturbed cure time at temperatures above 50°F (10°C). This ensures full shear transfer between plies, preventing the beam from delaminating when the Atir strap is loaded.

Phase 2: Positioning the Atir Strap

• Location: The strap is centered over the beam where it intersects a rafter or truss. For a ridge beam, the strap is placed perpendicular to the beam’s long axis, lapping over the top edge and down both sides.
• Bending: If using a flat strap, field-bend it to conform to the beam’s shape. Some prefabricated Atir straps come with a pre-formed 90° bend.
• Alignment: The strap must be plumb and centered. Any offset reduces capacity by up to 40%.

Phase 3: The 72 Fastener Schedule

• Fastener type: #10 x 1-1/2” or #9 x 1-1/2” galvanized hex head or bugle-head screws (or specified 10d x 1-1/2” nails with SDS coating).
• Pattern: The strap has pre-punched holes. For a “72 install”:
  • The strap is 72” long. It may have 72 holes (e.g., 3 rows of 24).
  • Install fasteners in all holes unless the engineer calls for alternating. Each fastener must penetrate the beam by at least 1-1/4”.
  • Use a torque-limited screw gun (for screws) or a positive placement nailer (for nails) to avoid overdriving.
• Edge distance: Maintain minimum 3/4” from fastener to beam edge.

Phase 4: Anchoring the Other End (Wall or Foundation) The bottom of the 72” Atir strap must extend down the wall studs and attach to a continuous sill plate or a concrete foundation via a mudsill anchor or epoxy threaded rod. The “72 install” may require 72” embedment into a grouted CMU wall core, meaning the strap is set during masonry construction.

Final thought

The Atir Strap and Beamd with 72 install is a pragmatic, robust approach for anyone needing dependable structural attachment across medium spans. With attention to loads, correct fasteners, and periodic maintenance, it delivers long service life and predictable performance—exactly what you want when you build for the long haul. atir strap and beamd with 72 install
