Abstract

In the past, a few investigations on modes of failures, have been put forward to determine the ultimate strength of composite beam. These determinations summarized elsewhere were on the mode of failure for reduced section of web of the composite beam subjected to monotonic loads. There has been a certain experimental works for a composite beam subjected to combined negative bending and axial load, and the mode of failure was reinforcement fractures. In this present study, a numerical model was developed for a composite beam subjected to combined negative bending and axial load, validated with existing experimental analysis, and applied openings with different sizes and shapes, which were a significant investigation on the mode of failure of reduced web section of composite beam subjected to combined negative bending and axial loads. In addition, the influences of degree of shear connection on failure mode with different shapes of opening such as circle and square were investigated. In summary, the reduced web section was found as substantial to influence a failure in the web of composite beam at any degree of shear interactions.
