72 Install: Atir Strap And Beamd With

Installing ATIR STRAP and BEAMD typically involves a multi-step process that varies slightly depending on whether you are using a standalone lock or a network (float) license. Standard Installation Steps

Prevents the beam from rolling or displacing laterally.
Transfers lateral (wind/seismic) forces into vertical resisting elements.

Required Tools and Materials for ATIR Strap and Beamd with 72 Install

Components:

ATIR straps (quantity determined by engineer – typically one per 48-72 inches of beam length)
72 fasteners per strap (specified: either 10d x 1-1/2" nails, #10 x 1-1/4" structural screws, or 1/4" lag screws)
Galvanized through-bolts (1/2" diameter) with washers and nuts
Heavy timber beam or engineered lumber beam (minimum 3-1/2" thick)
All-thread rod (if anchoring into concrete or steel column)

Load Assignment: Apply self-weight, nodal loads, and area loads. atir strap and beamd with 72 install

Typical use cases

Mounting small cells, RRUs, or radio units on street poles, utility poles, rooftops, and building beams.
Temporary or permanent installs for cellular densification, IoT gateways, or private LTE/5G deployments.
Sites where minimal structural modification is preferred (strap-based installs reduce drilling/welding).

Ignoring the Grain Direction: Fasteners near the end grain of a beam (within 2 inches) have 40% less withdrawal resistance. The 72 install pattern must start at least 3 inches from the beam end.
Mixing Fastener Types: Do not use drywall screws or common bright nails. Only use code-approved fasteners (e.g., Simpson SDS or 10d x 1-1/2” nails).
Short Fastener Penetration: For a beam with a 72” span, the required penetration into the main member is often 2 inches minimum. Check your local code.
Forgetting the 72-Inch Continuous Rule: If you space the strap in two 36-inch segments with a gap, you no longer have a continuous tension tie. The “72” implies uninterrupted strapping.
Over-tightening Screws: Stripping the wood reduces pull-out strength by over 50%. Use a torque-limited drill.

In high-wind or seismic zones (e.g., Seismic Design Categories D, E, or F), building codes often require a continuous load path from the roof down to the foundation. When you have a beam spanning 72 inches (or a repetitive spacing of 72 inches on center), the ATIR strap is specified to: Installing ATIR STRAP and BEAMD typically involves a

Step 2: Positioning the ATIR Strap

Place the ATIR strap flush against the beam. The slotted end should face the connection point (column or wall).
The strap must be perfectly aligned with the beam’s edge. Use a level to verify plumb.
Clamp the strap temporarily using spring clamps or quick-grip clamps.
