Abstract—The performance of buried continuous pipe lines during an earthquake has been a major concern as these structures are classified into the lifeline category. Moreover, the absence of any specific standard or guidelines for seismic evaluation of these structures in India has always called for site specific response evaluation. Post Bhuj earthquake, the Gujrat State Disaster Management Authority had initiated the study in a more holistic approach and Indian Institute of Technology, Kanpur came up with guidelines incorporating different provisions and commentary. The present article is a parametric study of pipe diameter on the seismic performance of the continuous pipeline system comparing different strain levels. Along with, the effect of installation depth is investigated. A case study on pipeline systems of Dehradun city, Uttarakhand (India) is also presented. Four different earthquakes are considered to generate near- field and far field effects. The study shows that pipes having diameters more than 2.2 m slip at any depth of installation.
