| Abstract: | In the light of the problem that the current seismic criterion can not satisfy the seismic design of long span cable-stayed bridges and taking Tangshan Caofeidian Industrial Area No.1 Bridge as the background, the article sets forth the seismic fortification criteria and performance objective of the project. According to the seismic design method based on the structural performance and the component capacity protection think, the study of earthquake motion parameters and the seismic performance of the whole... |
