Beam Supported by Shear Tab – Balloon-Framed

Beam is connected to wall panel with a steel shear tab welded to steel plate. Beam is connected to shear tab with bolts or welds. Plate is connected to face of wall panel using partially-threaded screws.

Purpose: Transfer of vertical load from steel beam to mass timber wall panel.

Design Notes

Capacity of the connection is dependent on the screw connections to the wall panel and the capacity of the beam to shear tab attachment.
Connection is capable of transferring out-of-plane loads between wall panel and beam where no diaphragm is provided.
Wall panel may be routed at steel plate for flush finish.
Consider horizontal slotted holes at shear tab connection for increased constructability and thermal movement.
Elevation control of shear tab is critical. • Constructability may depend on connection at opposite end of beam.
Beam cannot be disconnected from rigging until connected to shear tab.
With balloon framing, multi-story walls can be erected rapidly; however, constructability can be affected by the need for temporary bracing of walls.

Class: Class 2
