Seismic Response of Ductile Cast Iron Buried Pipeline with Socket Joint

Abstract:

By means of ANSYS finite element software, the numerical model of ductile cast iron buried pipeline with flexible joint was established, and the entire model was comprised of pipeline and its exterior massive soil for simulating the coupling-interaction between soil and pipeline. Meanwhile, the multi-point excitation method was adopted for considering the wave-passage effect. According to EI-centro seismic wave record corresponding to III site, the stress-time-history curve of pipeline body and the displacement-time-history curve of flexible joint were obtained, as well as the most dangerous parts might occur leakage were indicated, which provides the reference to the optimal design of ductile cast iron buried pipeline with flexible joint.
