EARTHQUAKE RESISTANT DESIGN CODES IN JAPAN, January,2000
The Hanshin-Awaji Earthquake on January 17, 1995, which resulted in more than 6,000 deaths, was one of the most disastrous earthquakes to hit Japan since the Great Kanto Earthquake of 1923. A large number of buildings and houses collapsed, while severe damage to highway and railway bridges seriously affected rescue and ambulance operations, and hindered restoration activities after the earthquake. Based on the lessons learned from the earthquake and the disastrous damage, the effort to strengthen and upgrade the seismic performance of civil infrastructures including highway, railway, port and harbor facilities and lifeline facilities was concentrated and the several seismic design specifications/guidelines and manuals have been developed and issued, and they have been effectively applied in the practical designs.
In January 2000, the Japan Society of Civil Engineers (JSCE) has published the third edition of the earthquake resistant design codes in Japan. This edition includes the newly-revised seismic design methods for civil infrastructures in Japan including highway bridges, railway structures, port facilities, water supply facilities and gas pipelines, as well as the lessons learned from the 1995 Hyogoken-nanbu earthquake and the key issues for the earthquake resistant design of civil engineering structures after the earthquake.
