ABSTRACT:

Flexible barriers with energy-dissipating devices are widely adopted as protection systems against natural hazards, such as rockfalls, landslides and debris flows. They consist of cable nets, steel wire ropes, energy dissipating devices (also called brake elements) and steel posts to transfer loads to foundations. A key feature is that these structures are light yet they can absorb high energy through the large elasto-plastic deformations and sliding node action. Structurally the flexible barrier system exhibits highly nonlinear behavior. In this paper, a new nonlinear cable element with sliding nodes is used to model sliding cable ropes and sliding ring nets. Thus, an integrated design method for flexible barrier is developed with deflections and stresses on all elements computed in an incremental-iterative nonlinear analysis. Simultaneously, a design chart for practical use of a type of flexible barrier was build based on the proposed model and analysis method for engineers to design the structure rapidly and conveniently.
