Building Drift
- Another important consideration in building design is to examine the
structure's potential for movement due to lateral loads. This is known
as building drift, Ds, or more specifically
story drift.
- UBC doesn't limit story or building drift due to wind, but does for
seismic in UBC '94 1628.8 or '97 UBC 1630.10
- Story drift - lateral displacement of one level relative to level above or below.
- General guidelines suggest limiting Dwind:
D £ (.0025) h as applied to masonry shear walls.
- Shearwall behavior is a function of shearwall length, L, to height, h, considerations.
