本論文主要在研究耐火鋼與普通鋼之角柱試體與邊柱試體在實尺寸鋼構實驗屋的真實邊界束制條件下之火害結構行為研究。火害實驗主要利用成大歸仁校區戶外試驗場中的一個既有鋼構實驗屋內北側兩個相鄰且打通的區劃空間(B區與D區)測試五支H型鋼柱試體,並將此五支H型鋼柱試體分為兩組進行實驗結果的分析與比較。本論文亦提出一套簡易的火害中鋼柱破壞溫度計算方法,利用簡易結構靜態分析模型並配合AISC (2016)規範中的梁柱交互作用公式來預測鋼柱於火場中的破壞溫度,此方法所得之鋼柱破壞溫度較為保守,且在建立結構分析模型和後續數值運算時,可節省許多的時間,適合於一般工程師與技師的使用,分析結果顯示:鋼柱在常溫所受之軸力載重比越高,其在火害中的破壞溫度越低,亦顯示出耐火鋼柱具有較佳的耐火性能。
This thesis mainly studied the structural behaviors of the corner-columns and edge- columns, made of fire-resistant steel and normal structural steel and under real end-restraint boundary conditions, in a full-scale steel experimental building subjected to fire. The fire test utilized two adjacent and interconnected compartments (B and D compartments) in the north side of an existing steel experimental building in the outdoor test field of NCKU’s Guiren Campus to test five H-shaped steel columns, and the five steel columns were divided into two groups (corner-columns and edge-columns) for experimental results analysis and comparison. This thesis also proposed a simplified method, which conducted a simple static structural analysis and employed the interaction formula in 2016 ASIC Specification, to compute the failure temperature of the steel columns in the fire test. The failure temperatures of the steel columns obtained by this simplified method were relatively conservative, and this method could save a lot of time when building the structural analysis model and implementing the subsequent numerical calculations. It is suitable for general engineers and PEs. The analysis results showed that the steel columns with higher axial load ratios at room temperature would have lower failure temperatures in fire, and the fire-resistant steel columns had better fire-resistant performances.
