In the paper a computation code based on the finite-element method for temperature evolutions in composite elements with internal cavities is presented. It is suitable for the analysis of various thermal problems encountered in mechanical and civil engineering such as fire risk assessment. It is based on a plane isoparametric triangular element with six nodes allowing the modelling of curved boundaries. In order to analyze composite steel-concrete elements and to take into account the non-linearities coming from the temperature-dependent material properties and from the boundary conditions, an implicit integration scheme is used. Another advantage of the program is the possibility of describing internal cavities with convection and radiation exchanges. In order to show the capacity of the program two examples are presented. Comparisons have been made with experimental and other numerical results, exhibiting very good agreement. [less ▲]

A uniaxial constitutive model for concrete at elevated temperatures is presented. The model takes into account the effects of transient creep as well as the effects of the initial load level. It is based on experimental tests on concrete cylinders and is here validated by comparison with experimental test on short restrained columns. [less ▲]

Reinforcing bars of 12 mm and 25 mm have been tested, at room temperature, at elevated temperatures (steady state and transient conditions), and after cooling from elevated temperatures. No decrease of the residual strength was observed as long as the elevated temperature has not exceeded 600°C. A slight decrease seems to appear for elevated temperatures beyond 600°C. Additional test for elevated temperatures higher than 680°C should ideally be performed to confirm this trend. [less ▲]

The standard fire resistance test is not appropriate for predicting the behaviour of steel frames under fire conditions. The simplified theories that have been published in approved national and international documents apply to some restricted particular cases of single elements (beams, columns). In most practical circumstances beams and columns are subjected to a combination of axial forces and bending moments and have variable restraint and displacement conditions at their ends. The problem is particularly complicated for columns. For this type of situation advanced computer programs can at the present time provide a satisfactory method for the determination of the fire resistance. This paper illustrates the preceding comments by evaluating the fire endurance of an unbraced steel frame with two loading conditions. [less ▲]
