| Abstract: | This paper studied the relevance of the seismic performance indexes and the model accuracy of high pier in the case of different divisions of the model, using the large finite element analysis software ADINA by the nonlinear time-history analysis. How to choose the minimum relevance performance indexes was discussed, and a reasonable advice of element division was given, the reference for the bridge seismic design is provided. |
