Steel Moment Frame Submittal Process

Strong Frame Moment Frame

The Simpson Strong-Tie Strong Frame® special moment frame connection is code listed under AISC 358-16, Chapter 12, ICC-ES ESR-2802 and City of L.A. RR25957. All designs, whether using the Strong Frame Selector Software, Simpson Strong-Tie engineering services or our provided load tables, follow the design specifications listed within. Specified frame designs are commonly incorporated into the Designer’s submitted documents the same as other selected and specified products. When designs are completed utilizing Simpson Strong-Tie design services, Simpson Strong-Tie can provide a stamped and signed package for the final submittal upon request. Deferred submittals are not recommended for lateral systems such as moment frames, because different prequalified connections have various design requirements for the connection and detailing. For example, the Strong Frame special moment frame does not require lateral beam bracing, whereas other special moment frame connections would require such bracing.

Below is a comparison of a factory-built special moment frame versus a field-welded special moment frame.
