Wind-resistant design manual for highway bridges in Japan

In Japan, wind-resistant designs of highway bridges up to the span length of 200 m are conducted according to the Wind-Resistant Design Manual for highway bridges. This manual is also applicable to the highway bridges up to the span length of 300 m with minor modification of its provisions. In this paper, the manual is outlined first to illustrate wind-resistant design procedure in Japan. Then turbulence effects included in the manual are described with Dr. Davenportʹs contributions to the manual.
