<h1>Strong Frame&reg; Special Moment Frames</h1>
	<h2>Inspection Requirements</h2>
	<p>Since the entire Simpson Strong-Tie Strong Frame special moment frame is designed to be field bolted, no field welding
is required. Welding for the frames is performed on the premises of a fabricator registered and approved in accordance
with 2015/ 2018 IBC Section 1704.2.5. Special inspections prescribed in IBC Section 1704 are not required for approved
fabricators. Nevertheless, all Strong Frame special moment frames are inspected by a certified welding inspector. Inspection
is also provided for the pretensioned bolts between the Yield-Link® stem-to-beam flange connections on top of the code
inspection requirements. Welding and bolting inspection documents as well as bolt preinstallation testing records can be
obtained from Simpson Strong-Tie at the request of the project designer or by scanning the QR code on the frame at
the jobsite.</p>

<p>Even though the Strong Frame can be field bolted and all field bolting is specified as snug tight, the latest IBC code references
AISC 360 and AISC 341 for bolting inspection requirements. AISC requires inspection prior to, during and after bolting similar
to welding inspections, although not much is required during snug-tight bolt installation.
In addition to field-bolting inspection, different building jurisdictions might have base plate grouting inspection requirements.
Please consult with your project building jurisdiction about this requirement.</p>
