ABSTRACT
Large scale fire tests on elements of building construction are extremely expensive and
there are considerable benefits to be gained if testing can be replaced by calculation.
Numerical heat transfer analysis can therefore play an important role in predicting the
effect of fire exposure on structural elements. In this paper, a two-dimensional finite
element method is employed to determine the time-dependant temperature distribution
in the cross-section of steel/concrete composite deck slabs exposed to standard fire
conditions. The effects of the temperature-dependent thermal properties of materials,
moisture content and boundary conditions have all received detailed study. A series
of careful fire tests, conducted by P.W. Haar et al[l], were utilised to verify the
accuracy of numerical
