000009800 520__ $$2eng$$aCyclic behaviour of two reinforced concrete exterior beam-column joints has been carried out under quasi-static testing with the objectives to investigate the hysteresis behavior of the beam-column connection, its failure mechanism, and evaluation of strength and ductility. The specimens have been fabricated in T shape and details are as follows (a) without confining the joint reinforcement and b) confining the joint reinforcement i.e. as per Indian Standard Code of practice on seismic design detailing. The size of the beam (275mm x 275mm) has been kept smaller than the column size (300x 300mm) but the main reinforcement (4 @ 20mm) is the same in both the components. The amount of transverse reinforcement in unconfined specimen is 10mm Ø @ 180mm in beam and 10mm Ø 300mm in column. In the confined specimen transverse reinforcement is 10mm Ø @ 100mm in beam and 10mm Ø @ 150mm in column excluding the joint region where confining reinforcement is 10mm Ø @ 100 mm. It has been observed that the strength in both the specimens is nearly the same while ductility of the confined joint is more as compared to unconfined specimen. The energy dissipation is more pronounced and also stable in confined specimen. It has also been observed that bond failure is leading to failure in attaining design beam strength due to insufficient anchorage.
