本文依實際試體尺寸進行的鋼結構梁柱接頭高溫受熱反應,以有限元素數值模擬模式來分析其高溫受熱中結構行為,並選用ANSYS為數值模擬工具;在材料組成律方面,因實際試驗用鋼材之高溫材料性質目前尚未測試,且國內相關資料亦不甚完備,本文先以歐洲規範EUROCODE 3高溫受熱環境下之鋼材性質資料,以作為數值模擬分析之用,進而透過程式分析建立一整套有關國內鋼結構梁柱接頭之高溫受熱行為,(如各種溫度下之梁柱接頭彎矩及轉角等關係),並以國外小尺寸鋼結構梁柱接頭高溫受熱試驗驗證本文分析模型之可行性。
本文主要敘述有鋼材高溫材料行為、數值模擬分析之建立與驗證以及兩種鋼結構梁柱接頭高溫受熱試驗之模擬,包含有定溫加載試驗與定載加溫試驗,主要以了解鋼結構接頭在高溫中其力學特性之影響參數以及非線性局部結構行為,以供後續研究整體鋼結構高溫受熱行為時之模擬分析使用。
According to the test of full-scale joints of steel sub-structure at elevated temperature,the composed beam-to-column subframe is analyzed by ANSYS finite code. The material properties of steel in high temperature proposed by EUROCODE 3 and CNS temperature curve are adopted.The feasibility of ANSYS numerical simulation model have been proven by modeling Al-Jabri's small-scale fire test.The moment-rotation-temperature relation of steel beam-to-column joint in high temperature environment is studied and the stiffness-temperature relation of steel beam-to-column joint is established.
