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

为了更好地了解界面特性与结构弯曲行为之间的关系，通过对同一批铸件的试件进行推挤和弯曲试验研究了粘接连接。研究了混凝土性能，截面和粘结缝几何形状或弯曲形态的影响。结果表明，如果避免了剪切破坏，则粘结连接可以实现充分的相互作用，与机械连接器相似的行为，并具有显着的结构延展性。还在弯矩，周期性载荷和蠕变载荷的情况下进行了弯曲测试，结果表明，在桥梁或建筑物常见的这些情况下，粘接连接也是有效的。最后将EC4规定应用于测试光束，并将设计结果与测量结果进行比较。差异仍然可以接受，表明Eurocode是保守的，可以用于设计具有粘结连接的钢混凝土结构元件。
