Suspension bridge hinged energy-consuming damping buckle structure
The invention discloses a suspension bridge hinged energy-consuming damping buckle structure. According to the suspension bridge main beam-main cable connection damping buckle structure, a C-shaped steel sheet is adopted as a damping energy dissipation element of a damping buckle, and the size of C-shaped steel is determined to meet the requirement of a suspension bridge for a central damping buckle by designing and calculating the technical parameters like the primary rigidity, the secondary rigidity, the maximum bearing capacity and the displacement-force curve of damping energy dissipationof the C-shaped steel sheet. The two ends of the damping buckle are connected to a main beam and a main cable of the suspension bridge in a hinged mode, and internal stress possibly generated by bending moment is released. A length adjusting structure is arranged in the damping buckle, and the problem that the performance of the damping buckle is affected due to difficult installation or uneven stress of the damping buckle caused by connecting hole pitch error on the main beam and the main cable as a result of bridge construction mistakes is mainly solved. The included angle between the damping buckle and the horizontal plane ranges from 25 degrees to 35 degrees, and force transmission between the main beam and the main cable and optimization of the structure of the damping buckle are facilitated.
本发明公开了悬索桥铰接式耗能型阻尼扣结构,悬索桥主梁‑主缆连接阻尼扣结构,所述阻尼扣采用C型钢片作为阻尼耗能元件,通过设计计算C型钢片的一、二次刚度,最大承载力,阻尼耗能的位移‑力的曲线等技术参数,确定其C型钢的尺寸满足悬索桥对中央阻尼扣的需求。所述阻尼扣两端采用铰接的方式分别与悬索桥的主梁与主缆连接,释放可能因为弯矩产生的内应力。所述阻尼扣内部设置有长度调节结构,主要解决因为桥梁施工误引起的主梁与主缆上的连接孔间距误差,从而导致阻尼扣安装困难或者阻尼扣受力不均而影响其性能。所述阻尼扣与水平面夹角在25°~35°之间,有利于主梁‑主缆之间力的传递及阻尼扣自身结构的优化。
