Research Seminar - Institute for Infrastructure Engineering

Title of the seminar: 'Structural Control: A Benchmark Model Study'

Under the background of the 3rd generation Benchmark problem on Vibration Control proposed by the International Association of Structural Control and Monitoring (IASCM), two new control strategies - structural adjacent reaction wall control (subsequently called “STA”) and mass-semi-active-damper (subsequently referred to as "AMD-2") - have been proposed, systematically evaluated, and compared with the Benchmark standard-extended active control solutions.

The comparison has also been extended to another reference strategy which is the structural interbedded control (subsequently called “STI”). A set of innovative evaluation indices, denoting the direction and energy relations between control force and its velocity and/or displacement, has been proposed to investigate the phenomena behaviour as well as intrinsic mechanism of active control force for each control strategy.

Based on thorough comparisons amongst different control strategies, the function of inertia mass of AMD system will be thoroughly discussed. Furthermore, the AMD-2 control strategy will be developed based on comprehensive analysis of STA control strategy, and both strategies will be intensively evaluated against Benchmark standard results.
