For long-span bridges, wind action is a dominant factor in their safety
and serviceability. A large number of long-span bridges have been built
in Japan over the past 30 years, and tremendous amounts of research and
technical development have been accomplished in wind-resistant design.
This book is a compilation of the results of active research and
development. Wind-resistant design standards generated in Japan are
described in the first few chapters. Then comes information such as
design wind speed, structural damping, wind tunnel tests, and analyses,
which provide the basis of the design standards. Wind-induced vibrations
and their control of girders, towers, cables, and other features are
explained with examples of field measurements. Comprehensive listings of
Japanese experience in vibration control are also presented. Because
achieving particularly dynamic safety against wind is still not an easy
task, these data and information will be valuable assets for the
wind-engineering and bridge-engineering communities.
