本研究共進行三組模擬懸臂梁之柱構件試驗，試體斷面尺寸皆為400mm(寬)×400mm(深)，柱主體淨高為1500mm，混凝土採用一般強度混凝土(fc’=21MPa)，搭配一般強度鋼筋(fy=420MPa)及一般強度箍筋(fyt=280MPa)。上述試體規劃主要探討典型鋼筋混凝土柱構件於各破壞模式受反覆載重下之裂縫發展及裂縫寬度與構件變形角之關係，透過Takeda遲滯模型與試驗結果進行比對，並將Takeda遲滯模型之力量-位移包絡線轉換為裂縫寬度與力量之關係及裂縫寬度與卸載勁度之關係，以作為損傷評估之初步參考依據，本研究亦參考AIJ-2004之裂縫與變形角評估模型，針對撓曲裂縫及剪力裂縫進行統計，提供台灣適用之裂縫比值，並建立典型鋼筋混凝土柱構件裂縫寬度與構件變形角之量化關係，以推估構件震後殘留變形角及震時之尖峰變形角。依本研究成果顯示，撓曲破壞及撓剪破壞其主要裂縫為通過主筋之撓曲裂縫，剪力破壞其主要裂縫為剪力裂縫，各試體預測之殘留變形角及預測之尖峰變形角趨於不保守，且由總裂縫寬度計算之變形角較能精準預測其變形角之變化，而尖峰撓曲變形量與尖峰剪力變形量分別佔總變形量之0.9倍及0.12倍，裂縫比值若採用平均值扣掉一倍標準差，各試體預測值所對應之裂縫寬度皆大於試驗量測之裂縫寬度，且各試體預測值之勁度皆小於試驗值之勁度，其結果視為保守狀態。

This study conduct three full-size experimental simulation of cantilever column member specimen with different failure mechanisms using general reinforced steel bars(fy=420MPa, fyt=280MPa), and the designed compressive strength of concrete is 21MPa. The purpose of this study is utilized Takeda hysteresis model compared with experimental results, moreover, Takeda hysteresis model of strength-displacement envelop will be divided into two portions, one is relationship between crack width and strength, and the other is relationship between crack width and unloading stiffness, as a reference to assess the damage quantification. According to the test result, the failure mechanism which is flexural and flexural-shear failure, the main crack is flexural crack width; however, the main crack for shear failure is shear crack width, and the angle of deformation calculated by the total crack width can accurately predict the variation, and the amount of flexural and shear deformation is 0.9 times and 0.12 times of the amount of total deformation respectively. If the crack width ratio adopt σ-μ, the predictive value corresponding to crack width of each specimen is bigger than the experimental result, and the predictive value of the stiffness of each test specimen are less than the test result, the results are seen as a conservative state.
