Axially loaded compressive tests on the CFSHS columnssubjected to the heating and cooling processes were performed.According to the test results, it is confirmed that the localbuckling before the occurrence of the overall buckling occurredin the specimens with B/t=31.3, on the other hand, the specimenswith B/t=15.6 exhibited the local buckling after that. In addition,the specimen after heating up to 300 ºC possessed the largercompressive strength than the specimen without the heating andcooling processes; however, for the specimen after heating up to500 ºC or the above temperature, the compressive strengthbecomes lower than that.
