This paper presents pull-out tests of perforated plate considering the difference of concrete placing direction and formula proposed for evaluating the shear strength based on the test results. These tests were carried out to apply the perforated plate shear connectors to the girder-topier rigid connections in a steel-concrete hybrid bridge. The shear force in perforated plate within the region of the rigid connection acts in all directions though the uniform direction is observed in usual composite girder bridges. Furthermore, the behavior of perforated plates is significantly complex compared with the headed studs, because of the existence of the void and laitance due to the bleeding in the holes. Test results indicate little difference in the ultimate shear strength of the perforated plate regardless of the concrete placing directions, and the proposed formula of the shear strength represent sufficient safety compared with previous test results.
