Assuming fixed boundary condition at each storey the wall rigidities of high rise buildings could be computed at each storey under the following
conditions:
- Relatively uniform arrangement of shear walls.
- Relatively long shear walls with fairly constant size from ground to roof.
- Reasonably symmetrical wall arrangement.
- Sufficient restraint is provided at each floor level by floors that are stiff relative to walls.
- Openings in walls are small enough to have negligible effect on shear distribution.
