Seismic Response Analysis Of The Continuous Rigid Frame Bridge Considering The Pile-soil Interaction

In recent years, several earthquakes are happening in the world, it not only allow people toawareness of the devastating and catastrophic of the earthquake, but also allow scholars begana more in-depth research about the bridge failure mechanism in the of earthquake and morein-depth study of the bridge structure seismic theory in the earthquake, it、s order is to putforward a better theory of seismic design method. The bridge project is not only played ahuge role in people’s daily life, after the earthquake, the bridge engineering is the lifeblood ofthe earthquake relief. With China’s rapid economic development, the span of the bridge isconstantly increasing, and the style of the bridge is also in constant innovation, so figuring outthe principle of the destruction of the bridge in the earthquake, increasing bridge seismiccapacity is a mission placed before the scholars and engineers.In order to study the impact of the pile-soil interaction to the continuous rigid frame bridgeunder earthquake response. This paper used the Ba Pan XiaYellow River Bridge asengineering background. Using Midas Civil2010limited element software established thefinite element model A that not consided the pile-soil interaction and model B that considedthe pile-soil interaction.Using the response spectrum method and time history analysis method calculated the modelA and model B.geting the displacement response and internal forces result of the Ba PanXiaYellow River Bridge under the condition of not consided the pile-soil interaction andconsided the pile-soil interaction. Comparing results of different models in the sameanalytical methods as well as the result with the same model under different analysis methodsdrawed the relevant conclusions that are benefit for similar bridges seismic analysis anddesign in the future.
