Steel-Concrete Connections by Adhesion, Interlocking, and Friction for Composite Bridges under Cyclic Loading

Jean-Paul Lebet, Dimitrios Papastergiou

This paper deals with of a new type of steel-concrete connection for composite beams. The connection is an alternative solution for steel-concrete composite bridges suitable for prefabrication and fast erection. The composite action of the beam is establis ...
