Sažetak
The paper presents test results of a study aiming to explore the influence of creep strain on reduction of the load- bearing capacity of fire-exposed steel and aluminium columns. The research focuses on the behaviour of columns made of steel grade S275JR and aluminium grade EN6082AW T6. Two types of high-temperature column tests were conducted in the study: constant-temperature capacity and creep tests. The temperature ranges for both capacity and creep tests are between 400-600°C for steel and 160-300°C for aluminium. The test results have shown that creep can reduce a steel column’s load-bearing capacity, even at 400°C. The influence of creep on load-bearing capacity, without prolonged exposure to high-temperature, can be observed when the axial compressive load is above 87% of the steel column’s axial load capacity. In the case of aluminium, creep starts to develop at approximately 160°C, at which the reduction in load bearing capacity is observed at loads above 88% of the column’s axial load capacity.
