    Abstract: 本實驗主要在探討已受損梁柱接頭採用鋼纜線混凝土擴柱補強方法的可行性,並由實驗結果中加以比較分析各試體的勁度、韌性、接頭剪力衰減及接頭混凝土剪應變等情形之差異 。 由實驗結果得知,鋼纜擴柱補強工法可以提高接頭剪力強度,使試體在接頭產生剪力破壞前先發生梁塑鉸破壞,但是補強成效仍不如預期,其主要原因為新舊混凝土面的剝離所導致。若是能在補強時,以植筋方式加強新舊面混凝土的握裹能力,則鋼纜擴柱補強工法應會發揮更大效果。 This experiment was mainly aimed at exploring feasibility of retrofitting damaged beam-column joint by wire concrete jacketing,and a discussion was made through the differences in stiffness, ductility, joint shear degradation between each retrofitted specimen。 From the experiment results,it was found that wire concrete jacketing scheme could improve the joint shear strength and make beam plastic hinge develop before joint shear failure。Howerver, the benefit of retrofitting does not come up to the target of the study because the split occurred in the interface between new and old concrete。It will improve the benefit of retrofitting by wire concrete jacketing if using anchoring method to prevent the split condition。
