Inclined cables are essential structural elements that are used most prominently in cable stayed bridges. When the bridge deck oscillates due to an external force, such as passing traffic, cable vibrations can arise not only in the plane of excitation but also in the perpendicular plane. This undesirable phenomenon can be modelled as an auto-parametric resonance between the in-plane and out-of-...

in this paper robust pid control of fully-constrained cable driven parallel manipulators with elastic cables is studied in detail. in dynamic analysis, it is assumed that the dominant dynamics of cable can be approximated by linear axial spring. to develop the idea of control for cable robots with elastic cables, a robust pid control for cable driven robots with ideal rigid cables is firstly de...

This study proposed three classic control algorithms (H2, H∞, Mixed H2 and H∞) to generate adequate controllers for either centralized or decentralized control of building structure using both cable and wireless sensing and control units. The complete control system contains three Magneto-Rheological (MR) dampers located on each floor of a 3-story steel-frame structure and tested it on a shakin...

Nagisa Bridge, a single span footbridge, was recently completed in Aomori prefecture, Japan. The structure of this bridge is a hybrid structure of cable-stayed prestressed concrete bridge and steel suspension bridge. It is the first application as this structure type of bridge in the world. Concrete girders near pylons are supported by stay cables. Steel girders are supported by suspension cabl...

In recent year, with recent increase of interest towards leisure sports, increased number of Zip-Line or Zip built. Many researches have been actively conducted on the emphasis of the cable and the wire at the bridge. However, very limite researches have been conducted on the safety of the Zip structure. In fact, fall accidents from Zip-Line have been reported frequently. Therefore, in this stu...

The damage caused by earthquake is irresistible for human beings, and the structure with poor robustness is most affected by earthquake. Especially when traffic arteries like bridges and highways are affected, the losses will be unimaginable. To reduce the loss in earthquake, the paper targets the long-span cable-stayed bridge and discusses a method of structural damage control. The energy-diss...
