Abstract:
The drift of multi-story flat plate buildings due to lateral loads of wind or earthquake affects the serviceability and the strength. The analysis for the drift has to be preceded by designating the components of the lateral force-resisting system (LFRS). Only the shear walls may be designated as the LFRS; alternatively, the LFRS can comprise all monolithic components of the building: shear walls, flat plates, columns and outriggers if any. This alternative is here recommended in the design of wind or earthquake. The basis and justification of this recommendation are given. The presented study employs linear analyses accounting for cracking as permitted by ACI 318. The work may be considered a pilot study; more extensive non-linear time history analyses need to be carried out before proposals for code changes can be made.
