摘要	The continuous pedestrian load time history can be got via the new micro electronic mechanical systems AH100B acceleration sensor and Fourier series loading model can be established through the experiment.In order to consider pedestrain-structure dynamic interaction, the human body can be made an equivalent as a biomechanical model with one degree of freedom of mass, stiffness and damping. And then the fitting expressions of the parameters of the pedestrian model, the step frequency and the mass of the human body are determined. Then selecting a two-layer cantilever steel bar truss deck slab of Gansu Science and Technology Museum as engineering background, using ANSYS finite element software to simulate the human-induced vibration response of the structure, The comparative analysis shows that the acceleration response is reduced by at least 10.59% after considering the pedestrain-structure interaction. According to the case that the maximum acceleration response of the structure exceeds the limit of serviceability index, the vibration response of the structure is controlled by a single tuned mass damper and a new 3-DOF tuned mass damper respectively. Both of them achieve better vibration damping effect, and the 3-DOF tuned mass damper with smaller damping is better. © 2018, Editorial Office of Journal of Building Structures. All right reserved.
