摘要：In a RC framed structure, beam-column joints are highly vulnerable to failure when subjected to seismic loads. RC framed structures constructed in accordance to pre-seismic codes will have deficiencies at the beam-column region, resulting in poor performance of the same when subjected to large lateral loads. In this study, six scaled down models of the beam-column joint of a non-seismically designed structure was prepared. Retrofit in the form of ferrocement jackets were applied on the con-trol specimen. Two types of ferrocement jacketing schemes were used, first one is the conventional square jacketing and the second is the advanced jacketing scheme in which the beam and column corners were rounded prior to the application of jackets. All the specimens were subjected to quasi static reverse cyclic loading. The experimental re-sults showed that there is an improvement in ultimate load carrying capacity, ultimate deflection, energy dissipation capacity and ductility for jacketed specimens compared to that of control specimens. The advanced ferrocement jack-eting technique was found to have slightly better perfor- mance compared to the conventional square jacketing.
