Shear connector characteristicsThe longitudinal shear that occurs between the concrete slab and the steel girder is due to the action of the following four elements:
- The joist shoes welded at regular intervals to the girder. This concept, patented under the name “Shear Shoe”, utilizes a secondary structural element (joist) to create the longitudinal shear of a primary structural element (girder).

- The anchorage created by the end plate welded at each end of the girder. The horizontal force is associated with the resistance of the concrete.

- The bond friction that occurs between the joist top chord S and the concrete slab.
- The additional connectors used to support heavy loads (U-shaped steel channels welded to the girder at regular intervals). These U-shaped channels were developed in collaboration with the Centre de recherche industrielle du Québec (CRIQ) and are always installed in pairs (one welded on the top of each angle of the top chord member).
