From the former earthquakes, plastic hinges of columns are more protuberant than plastic hinges of the beam which stretches intensification to global structural weakening and leads to loss of countless lives. Entirely the structural mechanisms pass their forces through the column and it further transfers it with foundation and finally to the soil, thus we can visualize if the column collapses whole structure can collapse, this is the concept of the strong beam and weak column. Enhancing the moment-resisting capacity of the column as compare to beams this results in the formation of plastic hinges in the beams first and avoids the global damage as the beam will show flexure as an indication of beam failure and the individuals will have tolerable time to vacate from that structure. The study is undertaken to explore the further behavior of the structure and for this investigation three RC frames of 5, 8, and 12 storey height are considered for strong column weak beam concept for Seismic Zone V, Soil type II and all the guidelines are followed as per IS 1893:2016. For inspection of the recital of plastic hinges of beam and column, non-linear static analysis is accompanied in FEM based software ETABS and the hinges are studied and confirmed conforming to accepted norms given in FEMA 356 and further base shear and performance point are discussed with displacement are checked for all frames
