| Abstract: | In order to reduce the structural vibration response and make full use of roof garden,a new tuned mass damper(TMD) vibration control system using roof garden is put forward,which is composed of roof garden on multi-story or high-rise building and laminated rubber bearing.The control principle of the roof garden TMD system is introduced,the parameter analysis of the system is performed,and the optimal damping ratio and frequency ratio of the system are obtained.Through an engineering example,the new vibration control method using roof garden is demonstrated,and the reasonable damping ratio and mass ratio are determined by using the advantage of adjustability of roof garden.Numerical analyses show that the roof garden has good control effect and the system performance is stable. |
