The present experimental work is concerned with the application of geogrid as partial transverse reinforcement in reinforced concrete beams and exterior beamcolumn joints. The composite advantages of steel fibre with minimum percentage and geogrid in resisting the shear force of beam and beam-column joint specimens with increased stirrup spacing under static and reverse cyclic loading are studied in detail. The loaddeflection curve, hysteretic loop, post-elastic strength and stiffness degradation, energy dissipation, failure pattern and damage tolerance capacity are the parameters used in this study to evaluate the performance of adopted new confinement technique. The improved shear carrying capacity with better inelastic response represents the advantages of the geogrid in RC structural elements. Also the enhanced energy dissipation and better damage tolerance of composite action provided by geogrid and steel fibre authenticate the use of synergetic effect in resisting the shear force in RC beams and beam-column joints.
