Measured and predicted behaviour of steel beams and columns in fire

Abstract
Analytical predictions of mechanical behaviour of fire-exposed steel structures are compared to experimental results obtained from three different research laboratories. Comparisons are made to axially free and restrained steel columns fire tested in Metz in France 1973-74, to simply supported steel beams fire tested in Germany and published in Stahlbau 1/1983 and to axially free and restrained steel columns fire tested in Trondheim in Norway in 1984. The measured time-temperature state of the steel structures is used as input information for the analytical prediction of the mechanical behaviour. For the analysis, the structural computer program Steelfire is used, Steelfire is a FEM-program and originates from NTH, Norway. The influence of... (More)
Analytical predictions of mechanical behaviour of fire-exposed steel structures are compared to experimental results obtained from three different research laboratories. Comparisons are made to axially free and restrained steel columns fire tested in Metz in France 1973-74, to simply supported steel beams fire tested in Germany and published in Stahlbau 1/1983 and to axially free and restrained steel columns fire tested in Trondheim in Norway in 1984. The measured time-temperature state of the steel structures is used as input information for the analytical prediction of the mechanical behaviour. For the analysis, the structural computer program Steelfire is used, Steelfire is a FEM-program and originates from NTH, Norway. The influence of the degree of axial restraint, load eccentricity and initial deformation in accordance to Dutheils formula are examined. Modelling of mechanical behaviour of steel also presented. Predictions and experimental results agree reasonably well, which illustrate the capability and reliability of the program Steelfire. (Less)
