A novel Link column system has been proposed for the seismic response reduction of Reinforced concrete structures. This paper presents experimental and analytical results carried out on single bay RC frames with and without link column. A design procedure is proposed to ensures that plastic hinges form in the links of the link column at a remarkably lower story drift than when plastic hinges develop in the moment frame beams. The link columns are designed as cantilever column to resist the lateral loads. Three models were considered for the study, i.e. without link column (M1), with rigid connection between main beam and column (M2) and with hinge connection between main beam and column (M3). The experimental investigation consisted of cyclic load test on the three models. Analytical Investigations using ANSYS was done to validate the experimental results. The test results showed that the energy dissipation of the link column frames increases significantly with a decrease in relative story drifts.
