Abstract:
Based on the cavity characteristics of reinforced concrete hollow-floor structural system, which was widely used in buildings at present, a rolling tuned mass damper(RTMD)which could be placed in the hollow-floor was proposed. The theoretical and experimental research on this kind of damping device was carried out, the calculation model of the interaction between the device and the structure was established, and the motion differential equation of the controlled structure was derived by using the Lagrange principle. The shaking table test of single-layer frame equipped with the device was carried out. The vibration reduction of the structure equipped with the device was studied by three kinds of dynamic action forms of free vibration, simple harmonic excitation and seismic excitation. Through numerical calculation and experimental study, the dynamic characteristics and damping performance of the system were analyzed. The results show that the proposed device can effectively reduce the dynamic response of the structure, especially the resonance response of the structure, and greatly reduce the resonance effect of the structure. The device does not occupy the use space of the building, does not affect the use function of the structure, so it can effectively solve the conflict between the setting of control device and the function of the building, and has a certain damping effect on the seismic response of the structure, so it has a broad application prospect.
