Aging of existing steel structures becomes a serious social and economic problem around the world, in both developing and developed countries where more and more structures become old and need to be strengthened or rebuilt. In comparison with replacement with new structures, maintenance or rehabilitation of existing structures have many advantages, such as relatively low cost in most cases, less disturbance on public traffic, less impact on the environment etc. In this paper, a research program for strengthening existing steel railway bridges is introduced. The design philosophy of the strengthening method, 7 loading tests (1 material test, 2 static tests on steel-concrete interface, and 4 laboratory and field tests on girder bridges, connections and columns) involved in this research and their brief summaries, were reported. The major aim of this paper is to report the research route, research methods and innovations of the research program, and provide a reference for engineering innovations in strengthening aged civil infrastructures.
