摘要
Based on a common electric furnace, a newly-developed built-up fire furnace equipped with liquefied gas burners is used to heat a structural column by electricity and blowing liquefied gas flame into the furnace simultaneously. Fire test results indicate that the hybrid heating method can be used to heat the test specimens closely following the ISO-834 standard fire curve, and can be used in fire test with excellent convenience and cost-effectiveness because it combines both merits of electric heating and liquefied gas fire heating. The proposed method provides a convenient way to simulate fire effects.
