A new construction method that is seismic strengthening method of existing reinforced concrete [RC] frame buildings by making use of steel braces or panels has been developed. In this method, a special mortar joint between steel elements with headed studs and existing RC frame with resin anchors is adopted. For new strengthened RC frames, experiments, statically non-linear simplified analysis on design level and more precise analysis are carried out. They are one-bay one-story frames about one-third of full scale structure. It is concluded that application of this new method improves the existing RC frames regarding both ultimate strength and ductility under large shear force, and non-linear behaviors for the strengthened RC frames are to be predicted in desirable accuracy by simplified analysis and non-linear static analysis.
