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.
