Large-span flexible corrugated steel culverts


The primary proposal's objectives are connected with realization of long-term field tests of large-span flexible culverts in full-scale under live loads and various climate conditions in Norway. The tests results will provide valuable empirical information and will contribute to better understanding of flexible steel culvert's behaviour in long time as well as developing and verifying design methods and optimizing of buried structures. Except the existing culvert, the new structures build over the training w ill be the main test subjects of tests.
Two existing structures located in Norway have been equipped with comprehensive instrumentation (earth pressure sensors, strain gauges, termistors) for long-term monitoring. Similar instrumentation will be provided to the new build long-span culverts. The important objective of the proposal is detailed analysis of tests results. Numerical culverts models will be created using the Finite Elements Method(FEM)and also FEM system for geotechnical purpose will be adjusted.N ext objective of the present proposal is the advanced research training of the applicant at Norwegian University of Science and Technology and ViaCon-Scandinavian culvert's producer.
During the fellowship the applicant will acquire experience in carrying ou t and managing the long-term field tests of culverts and will familiarize himself with methodology of designing and constructing in practice as well as acquiring proficiency in optimization analysis.
The applicant will also gain knowledge of programming numerical software for use in geotechnics. One of the aim of Human Resources and Mobility Activity is greater mobility of researchers in Europe as an instrument of knowledge and technology transfer as well as greater exchange of researchers between universities and industry. The proposal certainly meets this aim enabling the applicant to undertake research training in one of the leading European university in cooperation with an industrial producer.
