Embodiment Construction

[0027] Below in conjunction with example and accompanying drawing, the present invention will be further described.

[0028] The invention provides a method for improving the energy consumption capacity of prefabricated segmental assembled bridge piers. like figure 1 As shown, it is mainly composed of prefabricated segmental assembled pier, viscous fluid damper 12, steel sleeve assembly 7-8 with damper top support 9 and annular steel plate base 4 with damper bottom support 5. The ring-shaped steel plate 4 with the bottom support 5 of the damper is evenly welded with N rings of studs 15 along the perimeter, and the ring-shaped steel plate 4 is installed on the top surface of the bearing platform 1; after the pier body segment is assembled, the The steel sleeve assembly 7 8 with the top support 9 of the damper is installed at the joint position of the bottom section 2 of the pier body and the second section 3 at the bottom, and the locking plate 11 is locked with bolts 10; afte...

Abstract

The invention discloses a method for improving the energy dissipation capacity of a precast segment assembled pier, which adopts a set of anti-seismic reinforcement device composed of a steel sleeve,an annular steel plate, a damper and a matching connector, and is installed on the precast segment assembled pier. The method of the invention can effectively improve the energy dissipation capacity of the precast segment assembling pier under the earthquake action, does not need to bury the reserved parts in the original structure, does not need to carry out operations such as punching and the like that destroy the original structure, redesigns the original structure and partially reinforces the original structure, and the like.

Description

technical field [0001] The invention belongs to the technical field of bridge pier energy consumption, and relates to a method for improving the energy consumption capacity of prefabricated segmental assembled bridge piers by utilizing an external damper, specifically, a method for utilizing a viscous fluid damper, a steel sleeve and A method for improving the energy dissipation capacity of prefabricated segmental assembled bridge piers under earthquake action by means of a ring-shaped steel plate combination device. Background technique [0002] Since the pier body segments of the prefabricated section-assembled pier are all prefabricated in the factory, and only joint treatment is required during on-site assembly, and large-scale concrete pouring operations are not required, therefore, the prefabricated section-assembled pier has reliable quality and fast construction , has many advantages such as little impact on the surrounding environment. [0003] The huge advantages ...
