An innovative form of slim floor beams is proposed in which the shear connection is formed by combining the concrete passing through the web openings with a steel tie-bar element. A numerical study was conducted to evaluate the flexural behaviour of these composite shallow cellular beams. The force transferring mechanism, load-bearing capacity and failure patterns of the shear connections were also evaluated. Two different configurations of shear connection were designed and a parametric study was carried out to determine the parameters likely to influence their performance. The findings were incorporated with bending and push-out test results to develop design methods for this form of shear connection. A tentative design procedure for the composite shallow cellular beams is proposed.
