| 摘要 | This paper is aimed at the investigation of using suspended mass pendulums to reduce Wind-induced vibration of tall buildings. The tall building is modeled as a shear building with the same floor mass and lateral stiffness for each story, and the suspended mass pendulum as a single-degree-of-freedom (SDOF) absorbing system with a lumped mass hanged by a mass-less wire. Using the minimum-maximum amplitude criterion, one can determine the optimum parameters of the suspended mass pendulum for suppressing the steady-state harmonic response of the tall building under external excitations. By adopting the Davenport wind spectrum to describe Wind excitations, the vibration analysis of a tall building with 52 stories is employed to demonstrate the feasibility ofthe mass pendulum on mitigating the Wind-induced vibration of the building. According to numerical investigations, mass pendulums are useful devices to suppress the wind- induced Vibration of a tall building. |
