本文主要研究以複合材料補強鋼筋混凝土梁柱接頭之數值模擬分析，使用有限元素(Finite Element，FE)ABAQUS分析軟體模擬三維梁柱接頭與以CFRP(Carbon Fiber Reinforced Polymers)補強於鋼筋混凝土梁柱接頭構件之破壞行為分析。
本文探討之重點為一座外柱原型試體JE0，與兩座震前補強試體分別為JE1、JE2。其補強方式之差異，主要為CFRP黏貼方向，JE1的CFRP黏貼方向為水平方向，JE2的CFRP黏貼方向為對角方向。針對數值模擬提出一非線性模式，來預測鋼筋混凝土梁柱接頭補強後的強度和破壞模式，並與實驗所得的數據相比較作驗證。
本文分析結果顯示，外柱原型試體JE0以Kent與Park提出含箍筋圍束之經驗公式，其破壞包絡線接近於實驗曲線。兩座震前補強試體JE1和JE2，其分析結果兩者對接頭之層間剪力均有提升。本研究數值結果與實驗結果相比較，大致上建議之數值分析模式是可預測鋼筋混凝土補強後的強度。
本文參數研究為對於鋼筋混凝土梁柱接頭層間剪力之影響，分析結果可作為鋼筋混凝土梁柱接頭之影響因子。本文所提出之脫層數值模擬方面，其分析結果可預測CFRP脫層之發生行為。

In this study, a numerical analysis is proposed to predict the ultimate loading capacity of reinforced concrete (RC) beam column joints strengthened with the carbon fiber reinforced polymer (CFRP). Three full scale beam-column joints including two specimens strengthened with carbon fiber reinforced polymer (CFRP) and one control specimen are used to compare with the proposed numerical model.
The main parameters were investigated in this thesis including the shear strength of exterior beam-column joints the column axial load, effective slab width, ratio of column depth to beam reinforcement bar diameter, reinforcement confinement, ratio of column depth to beam depth, effective transverse beam, and the amount of CFRP.
Comparing with the test and analytical results, they agree well with each other. It demonstrates that the proposed numerical model can be used to predict the behavior of RC beam column joints strengthened with CFRP well.
