The Third PRC-US Workshop on Seismic Analysis and Design of Special Bridges was held October 21-22, 2004 at Tongji University in Shanghai, PRC. This workshop is the third in a series on special bridges in the U.S. and PRC and sponsored by the Federal Highway Administration. Hosted by Dr. Li Chu Fan, eight Americans and 20 Chinese engineers and researchers attended this year's workshop. Topics included bridge fragility analysis, construction materials for seismic resistant structures, near-fault ground motion, comparison of seismic bridge codes, nonlinear isolation bearings, test methods for bridge piers, risk assessment procedures, and case studies.

Formal presentations were followed by a tour of laboratory facilities at Tongji University. The university is one of the largest technical institutions in China with the Civil Engineering Department employing approximately 500 faculty and staff members.

In conjunction with the workshop, a technical tour was provided of a special bridge in the city of Hangzhou that was just completed and opened to traffic one week on October 16, 2004. The bridge has an overall length of 1073 meters and consists of two 190 m tied arch spans and nine 85 m deck arches. The primary structural members are concrete filled steel tubes. The substructure is supported on 230 bearing piles driven over the course of 11 months ranging from 60 m to 90 m in length. The bridge was constructed between March 2002 and October 2004 at a cost of approximately $120 million (USD).

After the workshop and technical tour, representatives of the USDOT Federal Highway Administration (Myint Lwin, Ben Tang, W. Phil Yen) traveled to Beijing to meet with government officials responsible for bridge technology in the People's Republic of China. The fourth workshop will be held in late 2005 in the U.S.

This is the third in a series of four workshops on special bridges sponsored by the Federal Highway Administration. Reviews of the first two workshops are available in Vol. 16, No. 2 (Spring 2002) at http://mceer.buffalo.edu/publications/bulletin/02/16-02/05_prc-usworkshop.asp; and in Vol. 18, No. 1 (Spring 2004) at http://mceer.buffalo.edu/publications/bulletin/04/18-01/04PRC-USbridge.asp.
