Four reinforced concrete frame using advanced retrofitting system, which is designed by the conventional method, retrofitting of ALC panel, k-type steel bracing system with steel frame, and retrofitting of steel plate with vertical & horizontal stiffener in R/C frame, were tested under both vertical and cyclic loadings, Experimental programs were carried out to evaluate and improve the seismic performance of such test specimens, such as the hysteretic behavior, the maximum horizontal strength, energy dissipation capacity, and crack propagation etc. under load reversals. All the specimens were modeled in one-third scale size. Based on the test results reported in this study, the following conclusions can be made. The specimens(RFAR, RFKB-F, RFSR-G) designed by the advanced retrofitting system for standard specimen(SRF) were increased 1.46~4.61 times in comparison with the standard specimen(SRF). Energy dissipation capacity of specimens designed by the improving of seismic performance were increased 2.14~5.01 times in comparison with the standard specimen(SRF).
