precast wall panel and steel frame
precast wall panel and steel frame
(OP)
We have an addition to design where the proposed construction is a steel frame with precast concrete wall panels. We don't often design this type of building, and I have a few question:
We are considering erecting a steel frame, and then having non-load bearing wall panels for the exterior. We would use the wall panels for shear walls only. Because it is an addition, there will only be shear walls on 3 sides, and the roof diaphragm will be steel wide rib deck. Does this sound reasonable? The building is in a low-seismic area.

Another way to go is to design an expansion joint between the old and new, and design your connections to transfer the shear, but allow for movement at the expansion joint. However, that detailing may prove to be to cumbersome and difficult to control and or install.
