The damage to water pipelines in past earthquakes includes numbers of leakage in jointed pipeline due to pullout behavior of non-anti-seismic joints. This paper reports on advantageous effects of rehabilitated pipe on the pullout behavior of joints in pipelines on which axial tensile load is acting, as part of the study on seismic improvement of pipelines with non-anti-seismic joints that are rehabilitated with a pipeline rehabilitation method. In the static and dynamic tensile tests conducted using sample pipes, rehabilitated pipe improved the preventive effect against joint pullout. In addition, this paper proposes to use the allowable strain of rehabilitated pipe as a performance index of anti-seismic capability to withstand strains that act in seismic motion.
