This book deals with behaviour of Exterior beam-column joints Using hybrid fibre reinforced high-strength concrete subjected to Seismic cyclic load. The experimental work is carried out to understand the effects of combination (hybrid) of steel fibres and polyolefin fibres in the non-seismic detailed exterior beam-column joints and its behaviour is compared with seismic detailed joints. The selection of materials, properties of materials, mix design, Specimen details and volume fraction of fibres, casting of specimens and testing of specimens for the above studies have been discussed.
