Fragility Analysis of Continuous Rigid Frame Bridge with Tall Piers
With the continuous improvement and development of highways and railways in western China, a large number of continuous rigid frame bridges have been built. In order to explore the response mechanism of tall pier and long-span continuous rigid frame bridges under earthquake, this study takes Wolonggou Bridge as the research object. The fragility under the action of horizontal and vertical earthquakes is studied in detail by the method of theoretical and numerical simulation. The results show that the damage of the pier exceeds the maximum probability under the action of longitudinal and transverse earthquakes. Under the longitudinal earthquake, the damage probability of the pier bottom is greater than that of the top. Under the transverse earthquake, the highest probability of damage occurs near the bottom of the pier.
