Preface of Structural Adhesive Bonded Steel-to-Steel Connections an Introduction for Structural Engineering Master Thesis by J.H.J. Flo.

This master thesis is the result of research carried out at the Structural and Building Engineering section of the Faculty of Civil Engineering and Geosciences at the Delft University of Technology. The research is an exploratory study on the applicability of structural adhesive bonding in the structural engineering. In search for a suitable thesis topic, I encountered a flyer about ‘Glued connections in steel trusses’. None of the courses which I followed throughout my student career treated adhesive bonding. I could only enumerate two applications of structural adhesive bonding in structural engineering on the spot; laminated timber and adhesive bonded carbon fibre strips for reinforcement. I wondered a few things.

Why aren’t there more well-known applications of structural adhesive bonding in structural engineering? What are the mechanics behind adhesive bonding? How strong are adhesive bonds? Is a full strength structural steel-to-steel connection with adhesive bonds possible? What are the possibilities of adhesive bonds? Enough questions for a graduate research and that is why I started this research.

Firstly, I would like to thank my graduation committee for giving me guidance, support and the opportunity to do this research. Also I would like to thank Bart Wiegant, Johan Boender and Fred Bosch of the Delft Aerospace Structures and Materials Laboratory. Without their help and advice during the fabrication of the double strap connections I certainly would not have been able to fabricate the connections with the achieved quality and strength. I am grateful to Berthil Grashof of the Delft Aerospace Structures and Materials Laboratory.

Without his help and explanation with the DIC equipment, measuring with DIC was not possible. I am grateful to Fred Schilperoort and John Hermsen of the Construction Laboratory of the Macromechanic (Stevin II) laboratory at the Faculty of Civil Engineering and Geosciences. Their help and advice during the tensile tests of the adhesive bonded double lap connections was essential for reliable test data. I am thankful to Gérard Hagmolen of ten Have and Mark Nieuwpoort of Sika for sponsoring my research with two sets of 6kg of Sikadur®-30 and for the additional information about some of the adhesives of Sika.

Last but not least, I would like to thank my girlfriend, Judith, for her moral support and for checking all the grammar and spelling. I hope that this thesis can take away some of the scepticism about structural adhesive bonded connections among structural engineers, architects and contractors. Hopefully this will result in an increase of adhesive bonded applications in the structural engineering.
