2、re safety. It is found that fire and the associ- ated effects on buildings is significantly different to other forms of loading such as gravity live loads, wind and earthquakes and their respective effects on the building structure。 Fire events are derived from the human activities within buildings
3、or from the malfunction of mechanical and electrical equipment provided within buildings to achieve a serviceable environment. It is therefore possible to directly influence the rate of fire starts within buildings by changing human behaviour, improved maintenance and improved design of mechanical a
4、nd electrical systems。 Furthermore, should a fire develops， it is possible to directly influence the resulting fire severity by the incorporation of fire safety systems such as sprinklers and to provide measures within the building to enable safer egress from the building。 The ability to influence t
5、he rate of fire starts and the resulting fire severity is unique to the consideration of fire within buildings since other loads such as wind and earthquakes are directly a function of nature。 The possible approaches for designing a building for fire safety are presented using an example of a multi-

The design of both the transfer structure supporting the building over the railway and the levels above the transfer structure are considered in the context of current regulatory requirements。 The principles and assumptions associ- ated with various a

8、his is not the case， to nearly the same extent, in the case of fire。 Rather， it is building regulations such as the Building Code of Australia (BCA） that directly specify most of the requirements for fire safety of buildings with reference being made to Standards such as AS3600 or AS4100 for methods

12、 The multistorey office building shown in Figure 1 is supported by a transfer structure that spans over a set of railway tracks. It is assumed that a wide range of rail traffic utilises these tracks including freight and diesel locomotives. The first situation to be considered from a fire safety per
13、spective is the transfer structure.This is termed Situation 1 and the key questions are: what level of fire resistance is required for this transfer structure and how can this be determined？ This situation has been chosen since it clearly falls outside the normal regulatory scope of most build ing r
14、egulations。 An engineering solution, rather than a prescriptive one is required。 The second fire situation (termed Situation 2) corresponds to a fire within the office levels of the building and is covered by building regulations. This situation is chosen because it will enable a discussion of engin
