SEISMIC RESPONSE ANALYSIS OF JOINT-CONNECTED BURIED PIPELINES INCLUDING CONCRETE-FIXED SECTIONS

By 尚男 後藤, 真太 杉戸, 弘行 亀田 and 厚志 磯田

Abstract

Estimation Equations for Strain and joint displacement of joint-connected buried pipes underseismic loads have been proposed. Response analysis of buried pipes for straight and concrete-fixed sections have been carried out with several analytical parameters as incidence wave, incidenceangle to longitudinal direction, and pipe diameters. Axial and bending strain, and joint displace-ment have been represented as a function of ground strain and apparent wave length in longitudinaldirection. Further, the effective construction method for concrete-fixed section which reducesbending stress of pipes there has been suggested.Estimation Equations for Strain and joint displacement of joint-connected buried pipes underseismic loads have been proposed.
