Structural performance of composite beam with trapezoid web steel section

Abstract

An experimental work on a composite beam with trapezoidally corrugated web steel section has been carried out to study its structural performance. A full scale composite beam test specimen with trapezoid steel section was tested under bending moment. For comparison, a specimen of composite beam with flat web section was also tested in the same way. Deflections, position of neutral axis, distribution of strain across the depth of the composite section were measured and analysed. The results show that the composite beam with trapezoid web has no significant difference in its structural performance compared to the composite beam with normal flat web.
