Comparative Study Of Bridge Seismic Design Standard Used In China And Japan

Earthquake is a precipitate natural disaster with great subversive. As bridge is the hingeof traffic, the importance of seismic design is self-evidence. China is a country with risk, sobridge designers pay more attention to seismic design. Since the “Highway engineeringanti-earthquake design specification” had been published in1st January1990, it has spent20years. With the great development and construction of Highway Bridge, the earthquakeengineering and seismic structural earthquake proofing technique discuss more deeply. It showsthat there’s still had some shortage in the standards, so the “the highway bridge seismic designrules” had been published in29August2008, which came into effect in1stOctober. Thestandard absorbs a lot of oversea design ideas, making us catching sight of the deepnessinternational exchange of design business.Japan is also a most frequent earthquake area in the world, which has strong economicresearch strength, experience and lessons on seismic design. They have set up a more perfecttheory and method in the part of highway bridge seismic design. Especially after undergo theOsaka-Kobe earthquake, by means of scientific comprehensive site inspection andexperimental study, the primary highway bridge seismic code have been reformulate andcomplete with latest seismic concept and research achievement. The current highway bridgeseismic code “Road bridge and recipe books seismic design article” was been issued in2002,which adopt more advanced seismic design concept, some seismic concept and methods areworth to learn.The paper compare the highway bridge seismic code used in China and Japan, so as tounderstand the idea of terms in code, found the difference from advance country. The seismicmethod in Japan was been used to the seismic design of reinforced concrete door type piers,the result has reference value for the practical engineering.
