FIRE RESISTANCE OF CONCRETE STRUCTURES

Abstract

A prediction of structural behaviour and fire resistance is presented for some different types of concrete members. This is made by use of two computer programs TASEF-2 and CONFIRE for thermal and structural response, respectively. Fire resistance times predicted by CONFIRE for different failure criteria and those obtained from different design recommendations are compared for a simply supported plate strip. The influence of axial restraint calculated by CONFIRE and by use of the PCI-manual are compared. Two column tests are also analysed successfully with the program. This paper is a result of a commenced co-operation in the structural fire engineering research between Lund Institute of Technology and SINTEF. Improved design methods and a more useful code is an important goal of the co-operation.
