RESEARCH ON ANTI-OVERTURNING PERFORMANCE OF MULTI -SPAN CURVED GIRDER BRIDGE WITH SMALL RADIUS
Since the severe situation of small radius curved girder overturning accidents in recent years in China, the research of anti-overturning performance with these bridges are becoming more and more important. In this paper, one small radius multi-span curved girder will be studied in the following procedure. Firstly, the requirements and application conditions of anti-overturning analysis methods at present will be summarized. Secondly, the finite element numerical model of the curved bridge will be built and some calculation and research on its anti-overturning performance will be carried out. Furthermore, the valuable conclusion will be drawn too, which can provide powerful practice and theory reference for the application and research of similar structure.
