In modern structural engineering—particularly for seismic resistance and load path continuity—ATIR straps (Advanced Tension/Inertia-Resistant straps) are critical components used to connect beams, columns, and shear walls. When combined with a beam and installed according to the "72 install" protocol, the assembly ensures ductility, energy dissipation, and code-compliant anchorage.
If using SDS screws, torque to manufacturer spec (typically 90-110 in-lbs). Check that no gap exists between the strap and wood. A gap of more than 1/32” voids the load rating. atir strap and beamd with 72 install
The beam (e.g., LVL, glulam, steel I-beam, or reinforced concrete) acts as the primary horizontal load-bearing element. When an ATIR strap is fastened across the beam–wall interface, it: the assembly ensures ductility
