Abstract

This paper presents an experimental study on the flexural behavior of three full scaled non-prestressed and prestressed composite beams with corrugated web, which had been developed by authors in their previous study. Also, the performance of the proposed flexural behavior model considering the accordion effect was examined, comparing to the test results. The test result showed that, due to the accordion effect before composite with the concrete, the introduced prestress in the top and bottom flanges of the steel beam has drastically increased, and that after composite with concrete, the flexural strength and stiffness of the prestressed specimens were superior to those of the non-prestressed specimen. It was verified that the proposed flexural behavior model accurately estimated the flexural behavior, before and after the composite with concrete, of the prestressed composite beams with corrugated web. Also, the horizontal shear strengths of the composite members, summing the average shear bond strength between steel plate and concrete and the direct shear strength of concrete, were evaluated considering the horizontal shear failure observed in the test specimens.
