If it is only an enclosure wall, then it should be arranged so that it is not part of the structural system, i.e., it is not a load-bearing or lateral force-resisting member, and it should not constrain the deformation of the structural system (vertically and horizontally). If a brick wall is placed between the columns of the steel framing, the lateral displacement of the brick wall, which is much higher than that of the steel framing, will result in the brick wall constraining the steel framing and cracking before the steel framing is stressed.displacement and cracking before the steel frame is stressed.Therefore, it makes sense to place the perimeter wall on a steel beam supported by bull legs, in which case the brick wall will move laterally with the steel frame without restraining the steel frame and will not crack.The skin (diaphragm) belongs to the lateral force-resisting components, we have said, enclosure wall flat, put into vertical, should not be called shear wall?
