In this thesis, an effective analysis model, named "equivalent column" model, was proposed for the wall inside the RC frames, and consideration the wall can resist axis force, moment, and shear force. The "equivalent column" model can simulate the brick wall, the RC wall as well as the wing wall. The experimental and analytical results of the RC column, pure RC frame, RC frame in-filled with RC wall, RC frame in-filled with brick wall, RC frame in-filled with wing wall, and RC column repaired by using the steel wire cables and the carbon fiber reinforced plastics were compared in the thesis.

中文摘要本研究主要分析补强前后含墙RC构架之耐震行为，目的是希望能合理有效地分析建筑物之侧向力与位移曲线，以利后续作为耐震评估之用，并考量墙体具有承受轴力、弯矩与剪力之较高自由度行为，以「等值柱」模型模拟含砖墙与含RC墙构架以及「墙柱」模型模拟含RC翼墙构架之耐震行为，分别对国内实验数据及理论分析方法-极限软化桁架模型进行比对。
