Plastic Hinge Analysis of Seismic Performance of High Bridge Pier
To analyze the second plastic hinge of high bridge pier formed in the earthquake and study the pier seismic performance, this paper takes the Kunming Slope Railway Bridge as an example. The simulation model was built by the elastic-plastic finite element ANSYS software. The buckling load of piers was calculated by buckling analysis capabilities of ANSYS software, a small enough initial offset given to the model, then the buckling load of piers put into the model. The deformation of non-linear model under the loads was calculated, the process was recorded that the reinforced concrete bridge piers initially yielding on the cross-section, continuously rotating around the neutral axis, and finally forming the eventually plastic hinges in certain parts of pier. The location of the plastic hinges can be inferred by final data of analysis software. By analyzing the calculated results, the seismic performance of the second plastic hinge in high bridge is studied.
