Abstract
The need for providing car parking within apartment buildings often lead to a situation where different grid arrangements exist in the parking and apartment floors. In most cases, a setback is also present to accommodate this change over. This requires the use of a transfer system such as a transfer plate or transfer beams. In mixed development, there is a possibility to change the location of the transfer floor. This paper explores the added advantage of using a transfer plate in such situations due to its outrigger behaviour and how it changes when its location is changed. A case study of a highrise apartment building is used to demonstrate different trends in outrigger behaviour with respect to dynamic wind and earthquake loading.
Highlights
With the rapid growth of urban development, high-rise buildings are constructed at an increasing rate
Often different grid arrangements exist in the parking and apartment floors that result in the need for setbacks and transfer systems
It should be noted that the transfer plate is generally located at the level of the setback, integrating the behaviour of the two components
Summary
With the rapid growth of urban development, high-rise buildings are constructed at an increasing rate. Many apartment buildings are among them, due to high land values in residential areas. In most cases, these apartment buildings will have car parking at the lower floors. Often different grid arrangements exist in the parking and apartment floors that result in the need for setbacks and transfer systems. With the popularity of mixed development, most apartment buildings tend to have shopping centers and various other facilities within the same building. With this recent development, the designer may have the flexibility to change the location of the transfer plate, affecting its outrigger behaviour. The behaviour of a transfer plate is investigated using Three Dimensional Finite Element modelling and its outrigger action is studied by taking into account the different loading conditions such as earthquake and dynamic behaviour under wind conditions, etc
