Research subject for a potential FP6 project

Development of a new generation of slender structural systems in civil and bridge engineering provided with intelligent joints and materials. The control of ultimate behaviour of such systems such as fatigue, resonance response, critical and postcritical static and dynamic stability behaviour, aeroelastic stability, vortex-shedding, galloping or flatter, etc. Load-bearing systems adopted are based on the combination of new materials, such as glass or carbon fibers, light concrete or laminated wood, with knowledge based multifunctional properties. Such composite structures are provided with intelligent control joints and material members. New advances in control joints and details as well as new ideas based on the above combination of various materials are to be focused in the scientific project suggested. The development of efficient procedures for linear and nonlinear analysis of intelligent structures and materials will be dealt with in ramification of the scientific project suggested. There is already not sufficient to be satisfied with being able to predict whether or not the slender structure will endure a certain loading environment without damage, but there is expected also be able to assess the damage for the case of an accidental overloading as well as for the case possible structural response.
