NUMERICAL AND EXPERIMENTAL STUDY OF A SLENDER CATENARY BRIDGE WITH A NOVEL TENSIONING SYSTEM

摘要

Catenary pedestrian bridges are apparently spreading all over the world. These structures are highly popular as they can form the landscape and provide the pedestrians with excitement and adventure. Consequently, there is a strong need to increase the span length, which might call for the reconsideration of the conventional approaches. A novel concept was proposed with special focus on feasibility and proper static and dynamic performance of slender catenary bridges. A dedicated physical model was built and measured in order to demonstrate the advantages. A long span catenary bridge designed in the framework of a feasibility study was also considered as an ideal candidate for our proposed method.
