Dynamic Control of Adaptive Structures
The build environment consists mostly of robust and static buildings, which are design to withstand the design loads prescribed by the Eurocode. Recent trends in architecture and structural engineering, such as form finding and material optimization results in a weight reduction, increasing the sensitivity to dynamic loading. An active control system can greatly improve the response of a structure to dynamic loading situations. However, many principles from control theory do not apply directly to buildings due to the deterministic character of wind and earthquake loading, and information on active vibration and displacement control is very limited. This research focusses on the numerical and experimental principles of control theory on structures, prone to dynamic loading and behaviour. To that extent, a numerical model has been made using a State-Space model in combination with an Euler-Forward scheme, enhanced with a Runge-Kutta algorithm. This intermediate colloquium will demonstrate the numerical model and its principles for a simply supported beam structure and will present the first results of the experimental research.
