New Steel-Concrete Shear Connection for Composite Bridges
This paper presents experimental and analytical research that was conducted on new connections "by adherence" for steel-concrete composite bridges. Their resistance is achieved by the frictional shear resistance of different interfaces positioned in a judicious manner. These connections make it possible to erect the structure quickly with full-depth precast concrete slabs, while the concreting works on site are limited as much as possible. Experimental results show that these connections exhibit a high resistance to horizontal shear forces and are very rigid compared to traditional connectors (headed studs). However, their ductility is limited. Based on the experimental results, a calculation model was developed and was used in a parametric study. Some results of the parametric study are presented and discussed in this paper. A simplified method for determining the resistance of these connections, design rules and recommendations for construction are proposed.
