An experimental study on behaviour of thjn walled cold formed steel-concrete composite beams under shear

摘要

This study investigates the shear capacity of cold formed steel channel section with lips, infilled with concrete by means of an experimental study. Tests are conducted on twenty four composite and twelve non-composite beams. Major parameters included in the study are shear span to depth ratio, depth to thickness ratio and cases of composite beam with and without shear connectors. Load carrying capacity, load and mid span deflection behaviour, ductility index, energy absorption capacity, slip and failure patterns are studied. This study also proposes an empirical equation using the experimental results, to predict the shear capacity of composite beams.
