Push-out and bending tests of steel-concrete adhesively bonded composite elements

Adhesive bonding connection was studied by means of push-out and bending tests performed on specimens cast in the same batch order to better understand correlation between interface characterisation structural behaviour. The influence concrete properties, cross-section joint geometry or configuration were investigated. Results showed that allows full interaction, similar behaviour than mechanical connector significant ductility if shear failure is avoided. Bending are also case hogging moment, cyclic loads creeping results shows efficient these situations usual for bridges buildings. EC4 provisions finally applied tested beams design compared measurements. discrepancies remained acceptable Eurocode conservative could be used steel-concrete elements with connection.
