Practical Application of Mass Type Damper for Wind-Induced Vibration Control of Super-Tall Buildings

摘要

In this paper, a mass damper was proposed and the plan on its practical application for windinducedrnvibration control of a super-tall building was introduced. The damper was developed torngenerate forces which were calculated by both linear and nonlinear control algorithms. A controllerrnin which the control algorithms were embedded was developed and it was verified throughrnexperiments that the damper with the controller could show dynamic behavior as a designer hadrnintended. A preliminary design of a super-tall building with the damper was conducted. As arnnonlinear algorithm, decentralized control algorithm which only requires to measure damperinstalledrnfloor response in order to calculate the control force was proposed. Simulation resultsrnindicated that the proposed damper could provide better or at least equivalent control performancernthan the usual active/hybrid type damper controlled just by existing linear control algorithms.
