抄録

Pipe stresses developed during earthquakes are influenced by the relative displacement of an ambient ground. The strains caused by the relative displacement of the ground are closely related to the magnitude of the earthquakes, the epicentral distances, the subsoil conditions, and the properties of the wave propagation in surface layers. Analyses of records obtained by a two-dimensional seismometer array observation at the Tokyo International Airport were carried out to evaluate the behavior of the pipelines during earthquakes. Pipe stresses are calculated from the ground deformation by the observation. The stresses calculated by the deformation method, which has been used for earthquake resistant design in Japan, and by the dynamic response analysis are compared with those from the observation.
