| Research Abstract |
Stub-column and column tests at elevated temperatures were performed for three different square hollow sections(SHS) of steel grade STKR400 in Japan. The main objective of these tests are to evaluate variations in the compressive behavior of steel columns due to different width-to-thickness ratios, to investigate the reduction of column strength by constant elevated temperatures, and to verify the accuracy of the finite-element model based on the shell theory. Especially it was shown that the deformation capacity of stub-column tests at various temperatures converged into almost a single curve.
