| dc.description.abstract | 本研究主要針對非韌性且低混凝土強度的RC柱，採用單向與雙向兩種不同的RC擴柱補強方式進行受力行為分析，討論補強前後的成效，並探討單向、雙向兩種擴柱補強方式下，理論與實驗結果的差異，以了解現今理論與規範之準確性與適用性。
由實驗結果得知，非韌性、低混凝土強度的RC柱經鋼筋混凝土擴柱補強後，其強度、韌性以及能量消散能力方面，都較原型試體有明顯的提升與改善，破壞模式也從原型柱的剪力與握裹破壞型式，轉變成為撓曲破壞型式。而單向與雙向擴柱補強方法之間的比較，經Mander圍束效應分析兩者斷面幾何形狀之差異，發現影響不大；然而，從實驗結果來看，單向擴柱補強試體在韌性、延展性以及能量消散的表現上，都比雙向擴柱補強試體差一些，值得進一步做整體構件分析之比較。

| dc.description.abstract | The purpose of this study is to observe the effectiveness for reinforcement concrete jacketing with one-way and two way RC jacketing. Also, the study analyzed the non-ductile original columns which simulated their substandard design in concrete strength and transverse hoops. To realize the feasibility in recent design standard, the difference between predicted and experimental results is studied.
From the test results, it was found that the retrofitted specimens are superior to the original specimens in strength, stiffness, and energy dissipation. Comparing the RC jacketed methods with one-way and two-way jacketing, the test results verified the specimen retrofitted by one-way RC jacketing is inferior to two-way RC jacketed specimen in ductility and energy dissipation.
