Acknowledgements
This thesis is the product of seven years part-time research with the last year even full-time to
complete the job. Many people supported, encouraged and stimulated me during these years
and this is my opportunity to thank them all and in particular the following persons below.
First of all, I would like to express my sincere gratitude to my promoters Frans van Herwijnen
and Frans Soetens for supervising this research work and their support. I profoundly
appreciate their comments, valuable remarks and suggestions throughout the duration of this
project. I owe a special depth of gratitude to Herm Hofmeyer, my copromotor. He kept a bird-
eye's view on the research project. He supported me by the design of the experiments and the
finite element models, and he has advised me to clarify the mechanical models. The other
members of the committee are also acknowledged for their comments, valuable remarks and
suggestions on the draft version of this thesis.
A lot of time was spent to carry out the experiments in the Pieter van Musschenbroeck
Laboratory at Eindhoven University of Technology. I would like to thank Hans Lamers for
also giving a short course about polymers, Theo van de Loo and in particular Martien Ceelen,
he was my help and stay through out the years. In this research, there was also a need for
assistance of other laboratories. I really appreciate the hospitality of Leon Govaert of the
section Polymer Technology of the department of Mechanical Engineering for using their
testing apparatus and Peter Cappon of the unit Building Physics and Systems of the
department Architecture, Building and Planning for using their chemical laboratory. I thank all
my colleagues at Eindhoven University of Technology, unit Structural Design and
Construction Technology for having a great time. I would like to thank Johan van den Oever
for helping me with all my computer problems and Mark Wolffe for adding books about
structural glass to the collection in our library. Many students I guided with master and
graduate projects related to my research project. I would like to thank them all and in particular
Bas Koggel who graduated successfully in 2006.
I would like to thank for supplying testing materials and guidance during my research in
particular Theo Rögels of Scheuten Glasgroep in Venlo and Berrie Roelofs of Sika
Netherlands in Utrecht. I would like to express my great gratitude to Anton Tapper of Façade
Consulting & Engineering in Eindhoven for his advices.
During the first 5 years I also worked part-time as structural designer at the engineering office
Volantis in Maastricht. I returned to Volantis in May 2009. I would like to thank all my
colleagues for their support and in particular Bert Schepers.
Last, but not least, I would like to thank my parents Pierre Huveners and Corrie Huveners-
Valkenhoff van Doorn, my uncle Michel Huveners and my partner Kristel Tijssens.

Circumferentially Adhesive Bonded Glass Panes for
Bracing Steel Frames in Façades
Summary
Contemporary architecture desires large glass surfaces in the building envelop with a minimum
of non transparent members such as steel braces needed for the stability of a building. Glass
panes have the capacity to resist in-plane loads and can replace the steel braces of a one-storey
building. The vertical stability system of a building is a primary structural component and has
to comply with strength (safety) and building stiffness (serviceability). A circumferentially
adhesive bonded joint is a suitable connection to introduce in-plane loads into the glass pane.
For the research three joint types have been defined. Joint type 1 is a flexible adhesive bonded
joint (polyurethane) across the full thickness of the glass pane. Joint type 2 is a two-sided stiff
adhesive bonded joint (epoxy) along the edges of the glass pane. Joint type 3 is a one-sided stiff
adhesive bonded joint (epoxy) along the edges of the glass pane. The steel frame, the single
annealed glass pane and one of the three joint types form the system which is only subjected to
a horizontally concentrated in-plane load at the top of the system. The objective of the
research is to get more insight in the structural behaviour of these systems and to set-up
mechanical models and possibly design rules. The research methodology consisted of
experiments, finite element simulations and parametric studies.
The experiments were carried out with square glass pane sizes of 1.0 m with nominal glass
pane thickness of 12 mm. Systems with joint type 1 had a very small in-plane stiffness of the
system, a glass-steel contact at large horizontal in-plane displacements at the top of the system
and a good residual capacity, namely large horizontal in-plane displacements at the top of the
system with increasing horizontal in-plane load. Systems with joint type 2 had much larger in-
plane stiffness of the system than systems with joint type 1. The residual capacity was very
good, because the horizontal in-plane load kept increasing after the first and following glass
cracks. Systems with joint type 3 had slightly smaller in-plane stiffness of the system than
systems with joint type 2. The residual capacity after the first glass breakage was very poor.
One finite element model for systems with joint types 1 to 3 was developed and calibrated with
experiments. The results of the finite element simulations matched well with the results of
experiments till the onset of the first crack in the glass pane or till the glass-steel contact for
systems with joint type 1.
The parametric studies only focused on the variation of the thickness, the width and the height
of the glass pane. For systems with joint type 1, the in-plane stiffness of the system depends on
the width-height ratio of the glass pane and the stiffness of the adhesive bonded joint. Systems
with the rectangular glass panes have two glass-steel contacts at increasing horizontal in-plane
displacements at the top of the system. Besides the stiffness criterion for vertical stability
systems of buildings the normal strain rate and the shear strain rate can also be a criterion. For
systems with joint type 2 and 3, the in-plane stiffness of the system is determined by the width-
height ratio and the thickness of the glass pane. The maximum principle (tension) stress in the
glass pane rapidly increases at the vicinity of the corners in which the ‘tension diagonal’ is
