Abstract
This paper presents a test study focused on determining the influence of high-temperature creep on the buckling of grade S275JR columns. Both capacity and stationary-creep column tests were performed within the study. The results obtained demonstrate that high-temperature creep influences a column’s load-bearing capacity, even at 400°C if the column’s load ratio is above 87%. The reduction of load capacity due to creep was determined experimentally up to 600°C, for which the failure due to creep occurred at load ratios above 57% of the capacity at 600°C. The failure times for all the column creep tests occurred within 240 min of loading at constant temperature. Numerical modelling of the creep tests, including their constant-temperature capacity, was performed with the help of the research software Vulcan, by explicitly including a previously developed creep model for grade S275JR steel in the total strain formulation.
