本研究以框組式木構造之間柱爲研究對象，探討間柱木構材於受火害時在變溫條件下之炭化深度預估模式，以期落實木構造技術推動及加強防火避難安全。研究採用本土木材與進口木材，以600、700與800℃三段固定溫度及CNS12514標準升溫模式之變化溫度，進行間柱木構材定溫及變溫加熱炭化實驗，於研究過程以濱田、菅原之定溫炭化評估模式及White標準升溫炭化評估模式進行實驗結果分析。研究成果顯示木構材在CNS12514標準升溫條件下，以分時段採用濱田、菅原定溫炭化模式與White標準升溫炭化模式比較，於加熱30分鐘時之結果趨勢相近。

The studs of wooden platform construction were deemed to be the subject in this study for the exploration of prediction models for the charring depth of wood under fires of variable temperatures. The purpose of this study was to promote wooden construction technology and to improve the safety of fire protection. The specimens for this study came from both native and imported wood. Three constant-temperature heating conditions-600, 700 and 800℃, and a CNS12514-compliant standard time-temperature curve, were applied to the charring experiments for framed wooden studs. The test results were analyzed against Hamada and Sugawara's charring models for constant-temperature heating conditions and White's standard fire curve. Comparing the afore-mentioned charring models applied to the test results under the heating conditions of the standard time-temperature curve, a fairly good agreement among the results was observed 30 minutes after heating commenced.
