本研究之目的，為探討各項參數對柱撓曲位移計算結果之影響，並與實驗結果進行比較。主要參數為有無圍束及不同圍束理論，其次即為箍筋形式、軸力、塑鉸長度之計算方式和斷面尺寸的大小。
結果顯示，有無考慮圍束效果於高強度混凝土試體之影響較大，而使用不同圍束模型進一步進行斷面分析時則幾乎沒有差異。計算側推位移時，以塑鉸長度多寡影響最為嚴重。軸力增加會提升柱之側推能力，但會降低位移能力。

The purpose of this study is to discuss important factors affecting the flexural deformation of reinforced concrete columns by using traditionally parametric analysis. These parameters are different confining models, different layouts of confining hoops, axial forces onto columns, plastic-hinge length models, and size of column sections.
The results show that confinement effect influences significantly on high-strength concrete specimens. The results obtained by sectional analysis using different confine model are more the same. Besides, the length of the hinge has the most severe effect on the displacement calculated. Moreover, increasing the axial force enhances the strength of the column, but reduces the displacement capacity.
