'Stress-ribbon
bridges' is the term used to describe structures formed by a very
slender concrete deck in the shape of a catenary. They can be designed
with one or more spans and are characterized by successive and
complementary smooth curves. These curves blend into the natural
environment and their forms, the most simple and basic of structural
solutions, clearly articulate the flow of internal forces which can be
erected without undue pressure on the environment. "Stress Ribbon and
Cable-supported Pedestrian Bridges" looks at how slender concrete decks
are used in the design of suspension and cable stayed structures.It
looks at their characteristic feature; their rigidity, which is mainly
given by the tension stiffness of prestressed concrete decking, so much
so that movement caused by pedestrians or wind does not register as
discomfort by users. Starting with a brief history the title describes
structural types, addresses general design criteria, current technology,
static and dynamic analysis and discusses the results of the static and
dynamic loading tests. Illustrated throughout, "Stress Ribbon and
Cable-Supported Pedestrian Bridges" provides examples of outstanding
structures, which have been recently completed. This book will be of
value to practicing engineers who wish to understand the premises upon
which the rules are based and researchers who wish to develop the
subject further and students who wish to delve into the background
behind the current loading rules.
