| 摘 要： | The control effects of a connected tall building structure with viscous damper in several respects were studied, such as internal force, deformation, acceleration and energy under dynamic wind load. Firstly, wind pressure time history data were obtained from the wind tunnel test of the structure model, and then a wind load processing program WINDHIST V2.0 based on wind tunnel test was developed, by which wind pressure data processed and inputted into Finite Element Method(FEM) program. Thus wind induced vibration time history could be analysed under various working conditions. It was shown that both the internal force and deformation of the connected structure with viscous damper can be decreased, while the effect of the former was more obvious than the latter. The acceleration at the top of the connected structure caused by dynamic response of fluctuating wind can be controlled effectively by viscous damper.
