Abstract:
The research reported in this paper was an investigation of the strength of the joint between a precast concrete beam and a cast-in-place slab when the composite beam was subjected to repeated loading. The test program included 29 beams and the principal variables where the amount of joint reinfocement, the roughness of the joint, and the ratio of the shear span to the effective depth of the beam. Equations are presented which yield a conservative allowable stress for the horizontal shear in composite members under repeated loads.
