    Cold Joint at Shear Wall to Diaphragm Connection. Check shear friction or not?

    Thank you guys for all your responses and research. Right now, I think the controversial part is whether we need to apply Omega factor to the horizontal shear transfer. I tend to agree with KootK that we should apply Omega since it is a critical connection. Actually it should be the first thing...

    Cold Joint at Shear Wall to Diaphragm Connection. Check shear friction or not?

    Hi, I am reading the design guide ''Seismic Design of Cast-in-Place Concrete Diaphragm, Chords, and Collectors''. In the guide it says ''Where the diaphragm is sandwiched between vertical wall segments, shear friction requirements must be satisfied through monolithic concrete at face of the wall...
