AU - Glisic, B.
N1 - Funding Information:
This study is based upon the work supported by the National Science Foundation under Grant No. 0936493 and realized in the frame of George E. Brown Jr Network for Earthquake Engineering Simulation Research (NEESR) Program Solicitation NSF 09-524. The tests were performed at The Cornell Large-Scale Lifelines Testing Facility, the NEES site at Cornell University (Cornell NEES Site). The authors would like to acknowledge the personnel of the NEES Site and in particular Mr Tim Bond, manager of operations of the Harry E. Bovay Jr Civil Infrastructure Laboratory Complex at Cornell University, and Mr Joe Chipalowski, the manager of Cornell’s NEES Equipment Site. This research has been awarded as a payload of NEESR Award CMMI-0724022. The latter hosted this research, and the author would like to thank all the collaborators from the NEESR Award for their precious help and in particular Radoslaw L. Michalowski and Jerome P. Lynch from University of Michigan, Ann Arbor, MI; Russell A. Green from Virginia Tech, Blacksburg, VA; Aaron S. Bradshaw from Merrimack College, North Andover, MA; W. Jason Weiss from Purdue University, West Lafayette, IN; Mohammad Pour-Ghaz from North Carolina State University; and their students whose help and shared experience significantly contributed to the successful realization of the test. The sensors, the reading unit, and the associated software were provided by SMARTEC SA, Switzerland at significantly reduced costs. Graduate students Dorotea Sigurdardottir and Yao Yao from Princeton University, and Kai Oberste-Ufer from Ruhr-University Bochum, Germany contributed significantly to the success of the tests and project in general.

N2 - Natural calamities such as landslides, sinkholes, and earthquakes, as well as man-induced events such as vandalism and terrorist acts, can cause significant deformation and damage to pipelines with potentially devastating humanitarian, social, economic, and ecologic consequences. Therefore, a real-time assessment of the condition of pipelines during and after such events is crucial. Distributed fibre optic technologies are ideal candidates for monitoring pipelines, due to their large spatial range, and relatively small spatial resolution. Nevertheless, practical manufacturing and implementation of distributed strain sensors, as well as their response to various actions is not yet fully understood. The aim of this paper is to compare performances of different distributed fibre optic strain sensors in terms of strain transfer quality, costs, and implementation approaches. Comparison is made qualitatively, based on experience, and quantitatively, through large-scale testing, by simultaneously exposing different sensors bonded on the pipeline wall and embedded in the soil in its proximity, to various levels of artificially induced permanent ground movement.
