An experimental investigation was carried out to study the effect of hybrid fibers on the strength and behavior of High performance concrete beam column joints subjected to cyclic load. A total of 12 reinforced concrete beams column joints were casted and tested. Design mix of M25 is chosen which is widely used in residential. Crimped steel fibers and Glass fibers were used in hybrid form. From cube tests, the volume fraction of (i) crimped steel fibers 0.75% (ii) glass fibers viz. 0.33% gives best results. Addition of fibers in hybrid form improved many of the engineering properties such as the crack pattern, ultimate load and ductility factor of the composite. The combination of 0.75% volume fraction of steel fibers and 0.33% volume fraction of Glass fibers gave better performance with respect to energy dissipation capacity and stiffness degradation than the other combinations. This project proposed that beam column joint is the weak zone where failure occurs and crack pattern is linear form. To resist the cracks, different types of fibers in linear form are introduced in the joint and also to improve the ductility property in the weak zone of the Beam-Column joint.
