Buildings are designed and constructed under the assumption that a fire can break out. In this paper, the numerical results acquired by three-dimensional thermal stress analysis which takes the influence of a concrete floor slab into consideration, three-dimensional analysis which doesn't do that and planar analysis, are compared with the experimental values for a large-scale steel car parking exposed to fire. The influence of a concrete floor slab on fire-resistant performance of steel frames has been discussed by examining of the results based on three analytical methods described above. It is demonstrated that the bimetal effect caused by the temperature gradient within a concrete floor slab exposed to fire could reflect a significant impact upon structural members which support the floor slab.
