Abstract

Continuous composite beams represent an efficient structural form in many structural systems, such as buildings and bridges, due to additional advantages associated with the favorable redistribution of internal forces across the member and the easier satisfaction of serviceability checks. Moreover, in the regions of hogging moments, e.g. at the internal support regions of continuous members, a large part of the composite beam section is subjected to torsional moment under certain loading conditions and in curved composite structures or flyovers, thus the bottom flange and the web are susceptible to local instabilities and the concrete slab may crack during its service stage. In this study, two steel-concrete composite beams were tested to investigate their mechanical performance under combined hogging bending and torsional moments. Load and deflection relationships, strain distribution and development in the reinforcement, and the slip on the steel-concrete interface were recorded in the test and reported in this paper.
