Preferred subjects for consideration

 1. Models, methods for cable dynamics analysis, including data analysis methodsThe first preferential subject is devoted first to the modeling of non-linear problems related to cable structures.This year, there will be place for papers about mathematical data treatment to evaluate records of vibrations either in frequency domain or time domain or both (FFT, matching pursuit, wavelet analysis, etc…) 

2. CFD and laboratory testing on cable dynamics problemsVirtual and actual wind-tunnel testing, including moving cylinders or actual cable configurations, with or without 3-D effects.For example (non-exhaustive) : CFD (Computational Fluid Dynamics) determination of wind power input to cable structures at large Reynolds numbers, CFD evaluation of wake effects, with comparisons to wind-tunnel measurements, limit of the quasi-steady hypothesis in different cable movements analysis, etc. 

3. Field experienceThis is a main concern of the symposium in relation to practical results from observations of any cable dynamics problems. It may also be devoted to any future large project that includes cable problems, to promote discussion and debate on the topic.For example (non-exhaustive) : recordings of significant events, results from measurements on large cable structures (occurrence of problems, observed damping, solutions proposed, etc), appropriate materials to be used, special techniques during erection using the properties of the cables, etc. 

4. RTM (real time monitoring)Due to increasing demand of sensors to evaluate in real time (or with small delays) the behaviour of structures, new sensors appeared on the market to help diagnosis of criticality of some situations, to understand and record rare events, to facilitate predictive maintenance, etc…  

Interaction between people from major engineering fields (mechanical engineering, electrical engineering, civil engineering) could help to the understanding of these complex phenomena and explore the ways to solve them.

The Symposium will be based on practical applications such as :

 overhead high voltage transmission lines

-  galloping, aeolian vibration and wake induced vibrations
- dynamic loading (turbulent winds, ice shedding, components breaking)
- structural frequencies and damping
-  the revolution introduced by real time monitoring

suspension and stayed bridges

- aerodynamic instabilities (induced by wind, wind and rain, ice, etc)
- parametric excitation of the cables
- changes of structural frequencies
- structural damping values

guyed masts

- fatigue life
- dynamic loading

high speed train catenary problems

- fretting ageing
- wave propagation and shock
