Validation of Solutions for Dynamic Analysis of Pipeline Systems by Comparing the Results of Calculations Obtained in the Russian CAE system APM StructFEM and in ANSYS as Applied to Seismic Resistance Problems

Modeling pipelines using special tubular finite elements is a convenient tool for the analysis of pipeline systems. Such a formulation significantly reduces the dimension of the problem being solved and significantly accelerates the time required to perform calculation procedures. These advantages can be explained by a modeling feature that involves the use of a pipe model in the form of a rod having an annular cross section. This paper presents solutions to the problem of dynamic analysis of pipeline systems, including analysis of the pipeline response to seismic effects. The work was performed to assess the reliability of the dynamic solutions obtained using the Russian CAE system APM StructFEM.
