An overview of our latest research and development is presented on structural system identification of damage detection devoted to reinforced concrete beams and steel-concrete composite beam-to-column joints under monotonic and cyclic lateral loads. Moreover, a real-time compatible algorithm for an adaptive technique in view of the control of structural systems is introduced. In detail, the use of Fibre Bragg Grating sensors for health monitoring of smart reinforced concrete elements and of accelerometers for detecting the variation of curvature and of stiffness in members and beam-to-column joints, respectively, by means of displacement mode shapes, demonstrate the feasibility and versatility of localised identification techniques and sensors to determine damage in view of the functional safety of structures. Moreover, a real-time compatible algorithm based on a Rosenbrock method is suggested for adaptive control systems which are generally used to control plants whose parameters are unknown or uncertain. The adaptive minimal control synthesis algorithm which is a direct adaptive controller is formulated in discrete form in view of a stability analysis of non-linear controllers.

Abstract
An overview of our latest research and development is presented on structural system identification of damage detection devoted to reinforced concrete beams and steel-concrete composite beam-to-column joints under monotonic and cyclic lateral loads. Moreover, a real-time compatible algorithm for an adaptive technique in view of the control of structural systems is introduced. In detail, the use of Fibre Bragg Grating sensors for health monitoring of smart reinforced concrete elements and of accelerometers for detecting the variation of curvature and of stiffness in members and beam-to-column joints, respectively, by means of displacement mode shapes, demonstrate the feasibility and versatility of localised identification techniques and sensors to determine damage in view of the functional safety of structures. Moreover, a real-time compatible algorithm based on a Rosenbrock method is suggested for adaptive control systems which are generally used to control plants whose parameters are unknown or uncertain. The adaptive minimal control synthesis algorithm which is a direct adaptive controller is formulated in discrete form in view of a stability analysis of non-linear controllers.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
