Abstract:
The skylines in the major cities of Sri Lanka are fast changing with many apartment buildings
being constructed. One of the primary requirements is the provision of car parking for which the lower
floors are generally used. The car parks will have a certain grid requirement for vertical load carrying
members primarily arising due to guidelines specified in building regulations. Often, this grid
arrangement is not suitable for apartments which generally consist of concrete walls that can become
part of the partition wall system of the apartments. Therefore, it is usual to have transfer girders or a
transfer plate to allow acceptable load paths for the vertical loads. When transfer plates are used in tall
apartment buildings, the wind induced acceleration could be an issue that needs careful consideration.
In this paper, it is shown that the transfer plates can be used as outriggers of the building is planned
carefully. Such outriggers have a tendency to reduce the wind induced acceleration to reasonably low
levels and hence become a useful feature despite the extra cost involved
