本文提出了一种理论来计算地面安装管道对地震激励响应的统计特性。假设管道的行为就像一个无限长的欧拉-伯努利梁均匀间隔的支持，地震运动是统计上平稳的时间，但在空间上的非均匀，和地震输入通过支持馈入管道系统，获得的结构响应的谱密度的解决方案。所发展的理论适用于任何谱分布。
This paper develops a theory to compute the statistical properties for the response of a surface-mounted pipeline to seismic excitations. Making the assumptions that the pipeline behaves like an infinitely long Euler-Bernoulli beam on evenly spaced supports, that the seismic motion is statistically stationary in time but nonhomogeneous in space, and that the seismic inputs are fed into the pipeline system through the supports, solutions are obtained for the spectral densities of the structural response. The theory developed is aplicable to any spectral distributions.
