Abstract

The oil pipeline bridge is an important component of the oil and gas transportation system, making the study of its seismic response and optimization of seismic design highly significant. This paper establishes a detailed structural model and evaluates the seismic mitigation effects of different seismic isolation and damping bearings under earthquakes of varying intensities through dynamic time-history analysis. The results indicate that stress concentration occurs in the pipeline bridge under seismic loading, with significant increases in displacement observed at the bearings, pipeline, and pier bottom during strong earthquakes. The appropriate selection of seismic isolation devices can effectively enhance seismic performance, with lead-rubber bearings (LRB) and high-damping rubber bearings (HDR) demonstrating superior performance. The findings provide valuable references for the seismic design and construction of such bridges.
