Vibration reduction structure of hollow steel floor slab
The invention provides a hollow steel floor vibration reduction structure. The hollow steel floor vibration reduction structure comprises a floor, a cross beam and a friction damping assembly. The two ends of the floor slab are connected with the cross beams on the two sides; the friction damping assembly comprises a plurality of stiffening beams which are sequentially hinged end to end; the stiffening beams at the two ends of the friction damping assembly are hinged to the cross beams respectively; friction dampers are arranged between every two adjacent stiffening beams and at hinge points between the stiffening beams and the cross beams; the friction damping assembly is arranged at the bottom of a floor slab, and the stiffening beam is fixedly connected with the bottom face of the floor slab. When the floor vibrates under the action of a load, the stiffening beam swings and rotates back and forth along with the floor, and the friction damper is used for generating a damping effect to dissipate vibration energy. When pedestrian excitation acts on the floor slab, the floor slab vibrates in the vertical direction, corners are generated between the stiffening beams and between the stiffening beams and the cross beams in the vibration process, the friction dampers generate a damping effect, and dissipation of vibration energy is accelerated.
本发明提供了一种空心钢楼板减振结构，其包括楼板、横梁和摩擦阻尼组件；所述楼板的两端与两侧的横梁连接；摩擦阻尼组件包括依次首尾铰连接的若干根加劲梁；摩擦阻尼组件两端的加劲梁分别与横梁铰连接；相邻的两根加劲梁之间以及加劲梁与横梁之间的铰接点处设置有摩擦阻尼器；所述摩擦阻尼组件设置在楼板的底部，所述加劲梁与所述楼板底面固定连接；楼板在载荷的作用下振动时，加劲梁随之往复摆转，所述摩擦阻尼器用于产生阻尼作用，耗散振动能量。当人行激励作用在楼板上时，楼板发生竖直方向的振动，加劲梁之间、加劲梁与横梁之间在振动过程中产生转角，摩擦阻尼器将产生阻尼作用，加快振动能量的耗散。
