Abstract

Abstract

The connection of square tube shear connector and H-shaped steel rib has been used in steel-concrete composite open-web sandwich plate recently. In order to study the mechanical properties of connection area, two full-scale specimens were manufactured to conduct contrast test and FEM analysis.The results showed that stiffening plate could make an obvious elastic-plastic behavior by seeting stiffening plate on the side wall of square tube shear connector. The stiffening plate could make a greater contribution to the tube's lateral stiffness and local stress concentration. Further finite element analysis showed that the width and thickness of stiffening plate, especially the plate width, had a significant effect on the stress distribution and lateral stiffness of shear connector.
