Wind-induced responses and control of a Kilometer skyscraper with mass and viscous dampers

摘要: Abstract The severe wind-induced responses of high-rise buildings can lead to safety and comfort issues. Thus, they need be controlled within an acceptable range. In this study, the a 4-tower-conjoined 1040-m-height skyscraper were first calculated based on wind load acquired from tunnel test. results implied that maximum interlayer displacement, displacement ratio, angular velocity building exceeded related criteria. particular, torsional response was significant, which revealed stiffness multiple-tower-conjoined should strengthen. Therefore, mass viscous dampers adopted control such Kilometer ensure comfort. Various schemes, including single hybrid methods, have been proposed by considering characteristics skyscraper. effects investigated compared. indicated method combining damper optimal for vibration rate reached 11% 46.8% translational residential responses, respectively. It demonstrated different methods may provide better effect some extent. Our investigation performed building, is expected useful engineers involved in similar structures.
