ABSTRACT
ABSTRACT: Determining the fire response of structural elements and their assemblies is a complex problem of nonlinear analysis in which the strength and the stiffness of the elements as well as the inner forces are continuously modified. To solve this problem the computer program FIRE was developed. The program was verified on the bases of the experimental investigation results available in literature. This paper describes the analytically achieved results for the fire resistance of centrically loaded RC columns. The influence of: element geometry, concrete cover thickness, steel ratio and intensity of axial force are analyzed. Four RC beams, exposed to different fire models are analyzed too, and the predicted results are compared with those experimentally achieved by other researchers.
