- Abstract
- This report summarises work carried out in a research project aimed at modelling, by computer, the performance of building components when exposed to fire. A finite element computer program (NISA) was used to predict deformations of steel beams. Useful results were obtained. The study concludes that the finite element computer program (NISA) is useful for analysing fire-resisting performance. Structural steel I-sections have been modelled in this study, with relatively good agreement being achieved between calculated and measured values for temperatures up to about 600 deg C. At higher temperatures the effect of steel creep needs to be accounted for. Further work is required to establish the same level of confidence for other materials and types of components.
