Abstract

Abstract
Modelling of full scale fire tests has led to new understanding of the behaviour of
structures under fire conditions . Much of this understanding has come from parametric
analysis using different finite element models. Outcome of each model depends on the
assumptions adopted in the structures idealization. Recent research es showed that behaviour
of indeterminate structures at high temperature changes drastically from its behaviour at
ambient temperature and large deflections experienced in real buildings during fire a re due to
restrained thermal expansion of steel members. However, slabs are the largest elements in any
building and it is expected to play a major role in distributing the applied load and
contributing to the stability of structures. Modelling of concrete slab at high temperature has
been the subject of several researches with different advantages for each model. This paper
describes a grillage slab model used to idealize the concrete slab at high temperature. This
simplified model has the advantage of ide ntifying the function of slab at high temperature and
providing a clear understanding of its contribution to the global stability of structure during
fire Finally the comparison of the developed models and experimental results show a good
agreement.
