Cable-stayed bridge damping supporting system and bridge
The invention relates to a cable-stayed bridge damping supporting system and a bridge, the cable-stayed bridge damping supporting system comprises a first component force device used for being arranged on a bridge pier, and the first component force device comprises a support for vertically supporting a main beam; the first energy dissipation assemblies are located on the two sides of the support in the transverse bridge direction and deform in the transverse bridge direction when the pier vibrates; the second component force device is arranged on the bridge tower and comprises a second energy consumption assembly connected with the main beam, and the second energy consumption assembly deforms in the longitudinal bridge direction when the bridge tower vibrates; the third energy consumption assembly is connected with the main beam, deforms in the transverse bridge direction and moves in the longitudinal bridge direction when the bridge tower vibrates; the bridge inhaul cable bears the main beam and is connected with the bridge tower so as to be matched with the first component force device and the second component force device to form a supporting system. Through the design of a cable-stayed bridge damping supporting system, disordered earthquake force of a bridge is orthogonally separated, space oblique earthquake input can be orthogonally decomposed into a longitudinal input part and a transverse input part, and energy dissipation and damping are conducted through a first force component device and a second force component device respectively.
本申请涉及一种斜拉桥减震支撑体系及桥梁，其包括：第一分力装置，其用于设置在桥墩上，其包括：竖向支撑主梁的支座；位于支座横桥向两侧的第一耗能组件，第一耗能组件在桥墩震动时横桥向变形；第二分力装置设置在桥塔上，其包括：和主梁连接的第二耗能组件，第二耗能组件在桥塔震动时在纵桥向变形；第三耗能组件与主梁连接，在桥塔震动时横桥向变形，纵桥向移动；桥梁拉索承载主梁，并和桥塔连接，以配合第一分力装置和第二分力装置形成支撑体系。通过斜拉桥减震支撑体系设计，将桥梁无序的地震力进行正交分离，可把空间斜向地震输入正交分解为纵向输入和横向输入两部分，分别由第一分力装置和第二分力装置来进行耗能减震。
