Novel energy dissipation and shock absorption type inter-tower connection structure of framing connected-tower cable-stayed bridge
The invention relates to a novel energy dissipation and shock absorption inter-tower connection structure of a framing tower-connected cable-stayed bridge. The structure comprises bridge tower bearing platforms, bridge tower columns are fixed to the bridge tower bearing platforms, the bridge tower columns are divided into upper tower columns and lower tower columns through bridge tower cross beams arranged on the bridge tower columns, and the bottom ends of two bridge towers are connected through a combined structure bearing platform straining beam between the bridge tower bearing platforms; inter-tower steel box inclined struts are arranged between tower limbs of the lower tower columns, so that the two bridge towers form local connection; and steel corbels are installed on the tower columns at the positions of the bridge tower cross beams, and dampers are installed between the two bridge towers through the steel corbels. According to the framing tower connecting structure form provided by the invention, on the basis of not influencing the construction period of the bridge tower and not increasing the construction difficulty, the transverse bridge direction earthquake response of the bridge tower is greatly reduced, and the anti-seismic property, the safety and the economical efficiency of the bridge tower are greatly improved.
本发明涉及一种新型耗能减震分幅联塔斜拉桥塔间联系结构，包括桥塔承台，在桥塔承台上固定有桥塔塔柱，桥塔塔柱由其上设置的桥塔横梁分为上塔柱和下塔柱，所述桥塔承台之间通过组合结构承台系梁使两幅桥塔底端连接；所述下塔柱的塔肢间设置塔间钢箱斜撑使两幅桥塔形成局部联系；所述桥塔横梁位置处塔柱上安装有钢牛腿，两幅桥塔之间通过钢牛腿安装有阻尼器。本发明提供的分幅联塔结构形式，在不影响桥塔施工周期、不增加施工难度的基础上，使桥塔横桥向地震响应大幅降低，极大的提高了桥塔的抗震性能以及安全性、经济性。
