Delivering structures that achieve their specified fire resistance is a key component of ensuring that the built environment is adequately resilient. The failure of buildings that are tall often has collateral consequences way beyond that of the immediate structural collapse. This paper describes the need for effective performance based structural fire engineering of tall or unusual buildings where the fire safety measures required to pass the standard fire resistance test do not necessarily

The case study of inclined columns in a tall building is used to illustrate this behaviour, and it is demonstrated that sufficient knowledge already exists for engineers to mitigate many possible failure modes. The columns are analysed when subject to a range of different heating conditions, and an analytical formulation is presented which can be used to improve the design of fire tall or unusual structure with inclined columns.
