The　cured-in-place-pipe　(CIPP)　liner　technology　involves　installation　of　flexible　polymeric　composite　liners　coated　with　thermosetting　resin　to　the　inner　surfaces　of　existing　buried　pipelines.　This　innovative　technology　provides　an　efficient,　economic,　and　environmentally　friendly　alternative　for　rehabilitation　of　structurally　compromised　underground　pipelines　without　expensive　and　disruptive　excavation.　However,　the　lack　of　analytical/numerical　procedures　to　quantify　the　seismic　performance　of　CIPP　liner　reinforced　pipelines　remains　a　barrier　to　the　seismic　design　and　rehabilitation　of　underground　pipelines.　This　paper　first　develops　an　experimentally　validated　hysteretic　model　of　ductile　iron　push-on　joints,　reinforced　with　one　particular　type　of　CIPP　liner　under　repeated　axial　loading.　A　numerical　procedure　is　then　proposed　to　systematically　assess　the　seismic　performance　and　fragility　of　straight　buried　pipelines　incorporating　push-on　joints　and　subjected　to　transient　ground　deformations.　The　numerical　results　indicate　that　CIPP　liner-reinforced　pipelines　exhibit　favorable　robust　seismic　performance　with　limited　joint　damage　under　high-intensity　transient　ground　deformations.　Copyright　(c)　2016　John　Wiley　&　Sons,　Ltd.
