Two half scale interior joint with monolithic transverse beams and slab from a six storied residential buildingwere selected for the experiment. The joints were constructed without any shear reinforcement within the joint regionto evaluate the contribution of concrete strength in bond stress between the longitudinal reinforcement and concrete.Bond stress has important specific roles on the ductility of the joint in particular and on the ductility of the globalstructure in general. The models were subjected to incremental static cyclic lateral loading provided by hydraulic jacksunder constant axial loading. Deflections and rotations were measured by dial gauges and a video extensometer. It isfound from the study that ductility of the structural members i.e. beams, columns and joints increased remarkably withincreased concrete strength. ER -
