Abstract

This paper deals with use of predictive models in analysing the behaviour of reinforced concrete components subjected to fire under loading. The main parameters considered are related to support specification e.g. simply, fixed and continuous support conditions. It is found that there is a significant variation of element performance in elevated temperature environment depending on support conditions. Furthermore, it seems that moment due to continuity could also enhance the structural performance at high temperature levels. In addition concrete strength, which influences structural performance, has also been taken into account. The analyses indicate that the beams have a particular flexural response, which depends on individual concrete strength within the early heating period. However, there is a "common" ductile behaviour when the heating time is above 3 hours.
