Vibration reduction structure of cable-stayed bridge
The invention discloses a vibration reduction structure of a cable-stayed bridge, and belongs to the technical field of bridge engineering. The fixing sleeve comprises an outer shell and an inner shell, the inner shell is arranged on the outer side of the stay cable, the outer shell is arranged on the outer side of the inner shell, a plurality of first ventilation openings are evenly distributed in the outer shell, a plurality of second ventilation openings are evenly distributed in the inner shell, the first ventilation openings and the second ventilation openings are arranged in a staggered mode, and drainage grooves are formed in the inner shell. The drainage groove corresponds to the first ventilation opening; and one end of the buffer piece is connected with the stay cable, and the other end of the buffer piece is connected with the inner shell. Wind and rain induced vibration can be effectively reduced, and the vibration reduction effect of the stay cable under the wind and rain action is improved.
本发明公开了一种斜拉桥减振结构，属于桥梁工程技术领域，包括：斜拉索；固定套筒，固定套筒包括外壳和内壳，内壳设置于斜拉索的外侧，外壳设置于内壳的外侧，外壳上均匀分布有多个第一通风口，内壳上均匀分布有多个第二通风口，第一通风口和第二通风口交错设置，内壳上设置有引流槽，引流槽与第一通风口相对应；缓冲件，缓冲件的一端和斜拉索连接，缓冲件的另一端和内壳连接。本发明能够有效降低风雨激振，提高风雨作用下的斜拉索减振效果。
