New technologies of steel bridges in Japan
Journal of Constructional Steel Research
Volume 58, Issue 1, January 2002, Pages 21-70
Abstract
Introduced in this paper are (1) some computer programs for static/dynamic elasto–plastic
finite displacement analyses used in designing steel bridge structures, (2) the ultimate strength
and design methods of steel plates, stiffened plates and columns made of high strength steel
subjected to compression, (3) seismic design and retrofitting methods of new and existing steel
bridge piers after the Hyogo-ken Nambu Earthquake, and (4) friction type joints and tension
type joints with high strength bolts and development of high performance high strength bolts
in Japan. These are some topics which the authors are concerned with among new technologies
of steel bridges under development in Japan, such as development of high performance steel,
new fiber materials, new types of bridges, performance based design methods, seismic design
method against earthquakes of level 2 like the Hyogo-ken Nambu Earthquake, and bridge
management system. 2002 Elsevier Science Ltd. All rights reserved.
