Embodiment 1
[0040] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0041] Such as figure 1As shown, it is an embodiment of a mass-tuned vibration-reducing multi-pendulum with air springs and damping particles in the present invention, which mainly includes: a rigid suspension rod 1, a tuning mass ball 2, an air spring 3, an anchor bolt 4, and a top hinge support Seat 5, reserved filling hole 6, damping particles 7.
[0042] The implementation steps are as follows:
[0043] 1) Multi-pendulum tuning vibration reduction for a 5-story reinforced concrete frame structure. The height of the bottom layer of the structure is 3.5m, the height of other floors is 3.1m, and the plane size is 55m×18m. It is planned to install a mass-tuned vibration-damping double pendulum with air springs and damping particles on the top of the building structure.
[0044] 2) It is determined that the diameter of each tuning mass ball...
