Research on Anti-overturning Performance of Multi-span Curved Girder Bridge with Small Radius

Abstract

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.

A security mechanism based on evolutionary game in fog computing

“…Their research results have encouraged and promoted extensive studies in this field. Lee et al (Lee et al, 2015, Xu, 2017) believed that the fog itself introduces special security threats. They discussed the concept of Internet of Things (IOT) of fog and existing security measures and established a safe fog computing environment by analyzing correlated security technology.…”
