A Brief Introduction on China Code for Seismic Design of Urban Bridges (2nd Draft)

摘要

The current highway and railway engineering seismic design codes in China are only applicable to the girder bridges and arch bridges with span length less than 150m, but not applicable to the long-span bridges and other bridges. Since 2000 A.C, the new China Code for Seismic Design of Urban Bridges has being compiled by our research group. The second draft of the new code has been completed in summer of 2003 A.C. Some problems in the new code were presented and discussed in this paper.
