- 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 temperatures on and within steel I-sections and concrete slab components. Useful results were obtained. The study concludes that the finite element computer program (NISA) will be useful for analysing fire-resistance performance. Common building components made of concrete and steel have been modelled in this study, with relatively good agreement being achieved between calculated and measured values. In general, results tend to over-estimate temperatures (rather than under-estimate) and for practical purposes this enables the program to be used with confidence for the types of components and materials included in this study. Further work is required to establish the same level of confidence for other materials and types of components. In further work it is intended to use the program to model the performance of concrete floors exposed to real (non-standard) fires, and to consider the effects of fire on structural behavior by calculation of the resultant stresses and deformations in structural building elements.
