Design Method for Connections by Adherence for Steel-Concrete 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 due to 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 which takes into account the deformation observed during the tests and the behavior laws for interfaces. This model was used in a parametric study. Some results are presented and discussed. A simplified method for determining the resistance of these connections, some design rules, and recommendations for construction are proposed. (A)
