Abstract
Seismic damage showed that the effect of earthquake damages on urban lifeline system is much larger than
other disasters. Shell element model of four nodes was used to simulate the buried pipeline, and the interaction between
soil and pipeline was simulated by nonlinear soil spring, seismic response of buried variable-diameter pipeline under
strike slip fault was analyzed by using finite element software ADINA. Through studying the influence of concentric and
eccentric variable-diameter on seismic response of pipeline, the conclusion was obtained that seismic capacity of
concentric variable-diameter pipeline is better than that of eccentric variable-diameter. The results of research provide a
certain guiding for the seismic design of buried variable-diameter pipeline across the fault.
