Wood Shear Wall on Moment Frame

[DJYork]

If you have a multi-story, primarily wood structure, with shear walls bearing on a steel moment frame. How do you typically transfer the shear wall forces to the moment frame? I have heard of different methods for this connection, but would like to get a broader idea of the construction techniques.

Bolts to the top flange of the frame.

Do you weld the bolts to t he frame, or do you offset and thru bolt it? Do you add stiffeners at the hold-down?

I weld studs to the top flange. Analyze the moment frame with overturning loads from the shearwall to see if you need stiffeners.
