Example Embodiment
[0025] The present invention will be further described below in conjunction with embodiments, but it is not limited to the following embodiments.
[0026] The invention is based on the conventional reinforced concrete bridge pier, the lower part of the bridge pier is designed into a steel tube concrete section with a reduced cross section, which reduces the lateral bending rigidity of the pier, and is supplemented by a mild steel damper to dissipate seismic energy to achieve seismic isolation the goal of. The structure is mainly used in bridge engineering and river crossing engineering with high seismic performance requirements.
[0027] figure 1 with figure 2 It is a specific implementation example of the connection method of a bridge pier and a cap with a soft steel damper. The construction method is mainly formed by corrugated thin steel pipes for placing the caps of the concrete-filled steel tube segments 1, reinforced concrete segments 2, and concrete-filled steel tube segme...
