PRC-US Workshop on Seismic Analysis and Design of Special Bridges

The PRC-US Workshop on Seismic Analysis and Design of Special Bridges is the first in a series of workshops to be conducted between bridge and earthquake engineering researchers in China and the United States. This first workshop was held in Shanghai, China, on October 8-10, 2002 at Tongji University. The next workshop is planned for the fall of 2003 in Buffalo, New York. Participation by the U.S. delegation was part of MCEER’s Highway Project, sponsored by the Federal Highway Administration.

The workshop focused on the seismic analysis and design of long-span bridges and those bridges that use advanced technologies to improve their earthquake performance.. Twenty-two papers on these topics were presented at the workshop, evenly divided between Chinese and U.S. experts. About 36 researchers and graduate students participated in the event. US delegates included George Lee, MCEER, Ian Buckle, University of Nevada, Reno, W. Phillip Yen, Federal Highway Administration (US members of the workshop steering committee), and Jamshid Ghaboussi, University of Illinois at Urbana-Champaign, Scott Ashford, University of California, San Diego, Harry A. Capers, Jr., New Jersey Department of Transportation, Charles Seim and John Sun, T.Y. Lin, International, and M. Saiid Saiidi, University of Nevada, Reno.

Lichu Fan and Mengling Lou, Tongji University and Weigang Bao, PRC Ministry of Construction, served on the Workshop Steering Committee for the PRC side. Other presenters included Li-ying Nie, Jun-jie Wang, Gui-ping Yan, Ai-jun Ye, Shi-de Hu, Yuan-de Xue, Jian-zhong Li, and Tian-bo Peng, of Tongji University, and Xi Zhu and Qing-shan Yang, Northern Jiaotong University.

The workshop included a technical study tour of the Lupu bridge, a tied arch bridge under construction over the Huangpu River in Shanghai. When completed next year, this bridge will set a new record for span length. At 550 m it will exceed the span of the New River bridge in West Virginia by 32 m. It will be the fourth long-span crossing over the Huangpu River, joining the Nanpu, Yangpu, and Xupu bridges, all of which are cable-stayed spans. The lead designer of the energy dissipation system in the main span was Professor Shi-de Hu, one of the organizers of the Workshop. Proceedings are anticipated in late 2002.
