Abstract

The invention discloses a post-earthquake recoverable assembled energy-dissipating pier structure, which comprises two supporting components arranged in parallel; the supporting components include several concrete pier columns; adjacent concrete pier columns on the same supporting component are connected by The components are connected; four oblique steel supports are intersected between two concrete piers on the same horizontal line on different support members; metal shear dampers are installed at the intersection of the four oblique steel supports ; The concrete pier column at the top is connected with the concrete cover beam through the connecting member; there is a metal energy dissipation section between the two concrete cover beams; several stiffening plates are welded in the metal energy dissipation section; both ends of the metal energy dissipation section pass through The bolts are connected with the steel plate of the non-energy-consuming section pre-embedded in the concrete cap beam.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a recoverable assembled energy-dissipating pier structure after an earthquake. Background technique [0002] my country is an earthquake-prone area. Under the action of earthquakes, civil engineering construction may suffer huge damage and lose its use function. Research and design of structures with recoverable functions after earthquakes must be an important topic in earthquake engineering. In addition, the prefabricated structure has significant advantages in terms of construction speed and quality assurance, and has developed rapidly in our country. [0003] However, the existing traditional pier structure has poor seismic resistance, cannot effectively dissipate the energy generated by the earthquake, and has no recovery ability after the earthquake. Contents of the invention [0004] The purpose of the present invention is to address the above-menti...
