Seismic Response Analysis of Joint-Connected Buried Pipelines Including Bent Sections

Abstract

Response analysis of joint-connected buried pipelines including bent sections has been carried out using analytical models, types of which are commonly used in the actual underground lifeline systems. The details of the structures and materials along the trunk routes of the Kyoto City Water Supply Districts have been intensively examined to establish these analytical models. Response analysis for four representative models of buried pipelines has been performed with some analytical parameters of pipe-structures, input ground motions, and soil springs, etc., focusing on the effects of the structural and input ground motion parameters on the response behavior of pipelines.
