I've got a steel framed multi-story building. I'm using ordinary concentrically braced frames (or at least trying to). I've put frames everywhere I possibly can in the structure, but the foundation forces are still unacceptable. A face of the building is CMU, as are two stair towers and the elevator shaft. In addition to my OCBF's, I'd like to engage these CMU walls.
What would be the relative stiffness between the OCBF's and CMU shear walls? What procedure would be used to determine both? E of steel and E of CMU are quite different (roughly 29:1), and I don't think my OCBF's will take 29:1 times more load than the CMU shear walls.
