Abstract
The effect of insulation on axial stresses induced in straight buried pipes due to earthquakes is investigated theoretically. Complex soil reactions are formulated for a viscoelastic medium composed of a softer inner ring and a stiffer outer layer. Seismic response of pipes is analyzed using both distributed and lumped mass models. The excitation is represented by traveling harmonic waves, fully-correlated transient waves, and partially-correlated random ground motion. It is found that insulation always reduces the stresses in straight pipes but this reduction is not as great as might be expected.
