摘要
This paper presents a material model for high strength concrete (HSC) at high temperatures. It includes all strain components in the mathematical stress-strain relationship. The main parameters of the model are the compressive strength and the modulus of elasticity. Their identification is based on own experimental tests [3]. The validation of the model was achieved with the results of a fire test of an axially loaded HSC column [4]. For the material behaviour of the reinforcement the Eurocode 2 (EC 2) [2] model with its properties was applied. The calculated displacements and the fire resistance time of the column as well as the material tests correlates well with the experimental results. Thereby it was found that the compressive strength has to be derived from transient creep and compressive strength tests.
