鋼筋混凝土是現今運用最廣泛的土木結構材料，其中混凝土材料在高溫中的行為結合了許多複雜的物理化學變化，普通混凝土及高性能混凝土之微結構的相異產生不同的現象。本研究指在探討鋼筋混凝土柱受到偏心載重於高溫中的變形，使用普通混凝土與自充填混凝土設計兩支鋼筋混凝土柱承受偏心載重，在高溫實驗中側試構件變形的行為。
在變形方面，柱所承受的載重較低時，軸向變形以膨脹為主。由高溫試驗觀察，自充填混凝土於高溫中爆裂嚴重，試體內部溫度偏高，同時也影響到柱之變形。
本研究以鋼筋混凝土學的基本理論及Eurocode2規範建議之公式以ANSYS的溫度預測結果，計算出柱構件在高溫中的變形，同時也能考慮到爆裂後縮減斷面的預測，預測值與實測值相當接近。

Reinforced concrete is now widely used in structure, and the behavior of concrete in fire is determined by complex physicochemical transformations. The difference of microstructure between normal concrete and high performance concrete have different phenomena during fire. For comparing the deformation and temperature distribution of eccentrically loaded RC column subjected to elevated temperature, we design two reinforced concrete columns placed by normal concrete and self-compacting concrete.
When specimen applied small axial force, the expanding axial deformation is observed significantly during fire. Because spalling of self-compacting concrete are seriously in high temperature, it affect not only the internal temperature but the deformation of the column.
At present, the deformation forecasting with many finite element method software has been quite accurate, the only drawback is that it cost too much time. To simplify the analysis, we use the basic theory of reinforced concrete and the formula recommended by Eurocode to calculus the column deformation. In process, we can observe the distribution of stress and strain in RC column section easily, and we can also consider the reduced section caused by spalling. Finally, there is a satisfactory results in the prediction.
