A laboratory research program carried out at the University of Waterloo featured the testing of three large-scale steel-concrete composite beam specimens with embedded bolt shear connectors. A detailed assessment of the connector performance was made, facilitating a comparison with similar beams with welded stud connectors previously tested in the same laboratory. It is proposed that the embedded bolt detail may be viewed as a viable alternative to welded studs, given the observed favorable fatigue performance and ease of deconstruction.
