Atir Strap And Beamd With 72 Install [updated] -

In a 140 mph wind zone, ASCE 7-16 calculates uplift pressure at roughly 30 psf. That’s on that connection. The ATIR strap with a proper 72-inch installation (continuous fastening over 6 feet) distributes that load across 24+ fasteners, each rated for ~100 lbs in withdrawal. The math works.

Starting from the joint and moving upward along the beam, install fasteners at . For a 36-inch run, that equals 12 fasteners (excluding the swivel plate). Stagger nails slightly if using two rows. atir strap and beamd with 72 install

If you shortened the fastening pattern to, say, 24 inches, you’d concentrate the load, likely causing fastener pull-out or wood splitting.

The analysis concludes that while the is highly conducive to rapid deployment due to its modular, bolt-together nature, the ATIR Strap system presents moderate risks within a 72-hour timeline due to tensioning calibration requirements and curing dependencies (if grouted). Successful execution requires precise pre-fabrication, parallel workflow staging, and strict adherence to torque specifications.
