Dynamic Response Analysis on Oil and Gas Shared Suspension Pipeline Bridge under Seismic Loading

摘要

Suspension pipeline bridge is a significant pipeline acrossing type.In particular?? when the pipeline goes through mountain and canyon terrain,suspension pipeline bridge is often used.For parallel pipelines of the oil and gas,shared across the project is inevitable.In this paper,it takes a oil and gas shared suspension pipeline bridge which the main span is 360 meters as the research object,use the finite element numerical simulation method to analyze the dynamic response under seismic loads.According to the analysis results,it determines the weak link of the structure under the seismic and evaluates seismic performance of the structure.
