| Abstract: | On the basis of investigation of the seismic damage to the simply-supported girder bridges in several violent earthquake events at home and abroad in the recent years,the seismic damage to the bridges is categorized and its causes are analyzed.In comparison of the relevant seismic specifications for bridges both in China and foreign countries,the insufficiencies of the current specifications of China are expounded,the performance of the simply-supported girder bridges used with the seismic mitigation and is... |
