Abstract:
Tuned Mass Damper (TMD) is a passive structural vibration control device which consists of a moving secondary mass connected to the main structure via springs and dampers. Pendulum Type Tuned Mass Damper (PTMD) is a type of TMD in which the secondary mass is suspended from the main structure. To design a PTMD, its optimal mass, optimal frequency and optimal damping are needed. In the current investigation, a model of G + 3 framed structures is considered and its response under sinusoidal base excitation is compared with and without PTMD. The main objective is to reduce the response of structure under resonant condition by using a PTMD. The different PTMD parameters are considered and analysed using software to determine their performance in reducing maximum displacement of structure due to dynamic loading. An actual model of framed structure with PTMD is then tested for base excitation by shake table analysis. Considering different PTMD parameters, the reduction in response of the structure is experimentally determined. The software and experimental results are compared and optimal parameters are determined.
