In this report the uses of adhesive bonding in civil and structural engineering applications have been briefly reviewed. Epoxy and acrylic adhesives are the most relevant types for load-bearing connections in structural steelwork. The techniques available for the quantitative design of bonded connections have been reviewed, and it has been concluded that there is a need for simple, easy-to-apply, design rules, and that there are grounds for believing that such rules can be devised for connections in structural steelwork. A thick adherend double lap shear (TADLS) testpiece has been developed for studying the properties of adhesive systems of interest. This showed that single-part heat-curing toughened epoxies were greatly superior to the other systems evaluated. Structural tests were performed on a generic prototype beam-to-column connection in which adhesive bonding was used to provide rotational stiffness. The results indicated that, whilst the adhesive clearly provided some degree of end restraint, a truly rigid connection was not achieved.
