ABSTRACT

The behaviour of steel and composite structures in fire are similar, therefore design methods for steel and composite structures in fire have many similar concepts and features. However, there is one significant difference in their behaviour; due to complicated temperature distributions in a composite structure, it is time consuming to implement in practice some of the general structural engineering principles given in design codes. Therefore, this chapter has the following two objectives:

1 to present the general F R design methods for principal composite structural members; and

2 to present, wherever possible, simplified calculation procedures for the implementation of the general design methods.
