Under seismic excitations, reinforced concrete building frames' beam-column junctions are crucial. Since these are some of the busiest places in reinforced concrete framed buildings, it can be very difficult to lay concrete and properly compact it there. Self-compacting concrete can now be used in a unique way since it can smoothly flow through every corner of a heavily reinforced region without vibrating. Therefore, self-compacting concrete can be utilised in place of ordinary concrete in beam-column joints provided it does not impair the frame's seismic performance. The application of high-strength self-compacting concrete in beam-column joints and an evaluation of its seismic behaviour under reversed cyclic loading are the main topics of this research. Three interior subassemblies of beams and columns are constructed with different concrete types and compressive strengths. The load, displacement/drift, ductility, joint shear deformations, and elongation of the plastic hinge zone are all measured on the instrumented specimens. Additionally, the method of failure and the pattern of cracking at various load levels are noted and compared across several specimens.
