During the past earthquakes, the insufficient seismic performance of low-rise to mid-rise reinforced concrete buildings due to the undesirable brittle shear failure of RC columns designed with pre-1971 Japanese design code has resulted in considerable loss of human lives and properties. Moreover, in order to satisfy the demand of high energy absorption by large seismic excitation, it is necessary to increase both the strength and ductility or only strength of the column. Considering this fact, a retrofit concept of thick hybrid wall utilizing additional concrete sandwiched by steel plates and high strength steel bar prestressing for bare frame either as opening type wing-wall or non-opening type panel wall is experimentally investigated and also analytically evaluated in this paper. The main goal of this research is to verify whether the proposed retrofit technique for bare frame is effective or not in respect of enhancing the story shear capacity and ductility.
