RESUMO
The Yuan-Shan Bridge System is one of the major projects currently under construction in this country. This system, when completed, is expected to alleviate drastically the traffic congestion around the Yuan-Shan area. Because of the great variation in the geometry of the system, a five-year research project has been issued by the freeway authority, Taiwan Area National Freeway Bureau, Ministry of Transportation and Communications, to the National Center for Research on Earthquake Engineering (NCREE) for the investigation of the static and dynamic behaviors of the bridge system. In this short article, a brief presentation will be made of the research topics that are currently undertaken or to be undertaken by the researchers in the monitoring and analysis of the static and dynamic behaviors of the Yuan-Shan Bridge System.(AU)
