Cyclic behaviour of beam column joint retrofitted with simcon laminates

An investigation on the performance of reinforced concrete beam column joints under cyclic loading is reported. Joints have been cast with adequate and deficient shear capacity and bond of reinforcements at the beam column joint. Fiber Reinforced Cementitious Composites (HPFRCCs) like Slurry Infiltrated Mat CONcrete (SIMCON) have been applied on the joints in different volume fraction and aspect ratios. The column subjected to an axial force while the beams are subjected to cyclic load with controlled displacement. The displacement is increased monotonically using a hydraulic push and pull jack. The hysteretic curves of the specimen have been plotted. The energy dissipation capacity of retrofitted beam column joints with various SIMCON configurations has been compared. In addition, comparisons were made between experimental and analytical results of control specimen and SIMCON retrofitted specimen. The results show that the strengthened beam column joint exhibit increased strength, stiffness, energy dissipation and composite action until failure.
