A 10-story reinforced concrete building with the dimensions
Neglecting the framing action between columns and slabs, it is required to estimate
1. the relative stiffness in Y-direction between the shear walls and the frames
2. the percentage of the lateral load that will be resisted by the shear walls
3. the relative stiffness in Y-direction between the shear walls and the frames after adding a reinforced
    concrete bracing
