Creep analysis of steel columns with different heating rates
This article presents benchmark studies, which include explicit creep analysis, for steel columns exposed to fire. Simply supported steel columns within the range of slenderness 20-120 were heated at different rates in order to calculate the development of creep strains and their influence on column critical temperatures. Two different creep models, based on time and strain hardening rules, were used in the analyses. The results of the benchmark studies have shown that the reduction of a stocky column’s critical temperature is typically approximately 10% from that of the same column determined without considering creep. The level of reduction is more pronounced for the higher levels of slenderness, illustrating that creep strains act as an amplifier of the effect of geometrical imperfections. The benchmark results have also shown that, beyond the heating rate of 10°C/min which was the highest used in these studies, creep strains have little influence on the column critical temperature.
