- Abstract
Based on the restriction of Chinese seismic design criterion which is only applied to regular bridges whose column heights are lower than 40 m, a typical high pier and long span rigid bridge is used in this study The typical nonlinear numerical analysis model is built for long-span continuous rigid frame bridge with high piers based on the fiber model. A special Pushover method is proposed for nonlinear analysis on the structure under the earthquake in longitudinal and transversal direction respectively. Incremental Dynamic Analysis method is performed with the nonlinear dynamic history analysis for comparison the results. At the same time, the application of the two methods in the continuous rigid frame bridge is analyzed and compared. The analysis results show that the Pushover and IDA analysis method can be used to evaluate the seismic performance of high pier continuous rigid frame bridge.
