Thermal response of a composite floor system to the standard fire exposure

Abstract

This paper discusses the development of a finite element model (FEA) of a full-scale composite floor system and application of this model to predict the heating of steel members when exposed to a standard fire during fire resistance experiments. The model is verified by comparing the predicted heating profile of steel members at several locations during the tests with measured data. Such a verified model can be used to characterize the uncertainties in the prediction of the thermal history of structural elements exposed to a damaging fire. The output of this model can be used in a subsequent structural analysis model to determine the nonlinear behavior of structural members due to both thermal and mechanical loads. Additionally, the thermal effect of possible concrete spalling events and the resultant fireproofing dislodgement from steel members were numerically investigated and compared with measured data to determine the efficacy of the heat transfer model.
