Abstract
In order to investigate load-carrying capacity, ductility and plastic development of orthotropic steel-concrete composite deck used in composite girder cable-stayed bridge, six single-point-loaded simply-supported orthotropic steel-concrete composite decks with varying axial compressive forces and different concrete grades were designed and tested. The test results show that the failure modes of all specimens are similar and exhibit cracks of the lower concrete section combined with crushing of the upper concrete section at midspan. The axial compressive force imposed in this test has a neglected effect on elastic stiffness and vertical load-carrying capacity of tested specimens. While the axial compressive force considerably lowers the ductility and plastic development of the orthotropic steel-concrete composite deck under vertical load. Besides, improving concrete grade from C60 to C80 could not help to enhance elastic stiffness, vertical load-carrying capacity, ductility and plastic development of the composite deck.
