Abstract:
This project has been concerned with the strength of the joint between precast concrete beams and cast-in-place concrete slabs. In the experimental program 42 beams and necessary control cylinders were tested in an attempt to provide information on the following variables: degree of roughness of contact surface, length of shear span, percentage of steel across the joint, effect of shear keys, position of the joint with respect to the neutral axis, and concrete compressive strength. Results obtained indicate complex relations between roughness of surface joint, percent steel across joint, and shear span.
