| Summary: | This paper presents the potential of plywood as a part of structure in high rise building in order to suppress dynamic unbalance activity. In this study, a miniature 7-storey high rise building is developed using plywood materials. In additional, a Tuned Mass Damper (TMD) control scheme is applied in order to have better harmonic absorber mounted at a bottom of the structure to prevent discomfort of sway at horizontal axis. The bottom floor of TMD is modeled as a nonlinear spring mass system and the total energy is only due to the elastic potential energy coming out from the earthquake. This TMD is obtained using Lagrange and D’Alembert method from a two degree of freedom (DOF) vibration structures. Then frequency response function (FRF) experiment was developed to analysis the responses of high-rise building in order to get the feedback response when a continuous excitation is applied at the horizontal axis of the ground structure. As a result, plywood materials are able to absorb more energy during the earthquake. Finally, with a better control scheme, the analysis shows no different at FRF but a 5 degree lower different in phase from baseline experiment. |
