Abstract

The invention relates to an elastic swinging column with replaceable bending dampers. The elastic swinging column comprises an elastic swinging column body and steel bending dampers, wherein the elastic swinging column body comprises a column base and a steel column; each steel bending dampers is fixedly connected with the column base through a large hinge and high-strength bolts; the large hingeis fixed on the column base through foundation bolts; each steel bending damper is connected with the steel column through a small hinge and the high-strength bolts; the small hinge and the steel column are fixedly welded; at least one steel bending damper is arranged on each side of the steel column and symmetrically distributed; every two steel bending dampers are spaced; the included angle of radians between the two ends of each steel bending damper is 60 degrees; and the plasticity and strength of materials of the steel bending dampers are limited. The elastic swinging column has the beneficial effects that the earthquake damage is reduced, and the steel bending dampers are replaceable.

Description

technical field [0001] The invention relates to the field of building technology, in particular to building shock absorption technology, in particular to an elastic swing column with a replaceable bending damper. Background technique [0002] Earthquakes are one of the disasters that cause serious damage to buildings. Bridges and buildings with reasonable design and fine structure often show good performance under strong earthquakes. But the repair and demolition of damaged structures after earthquakes, mainly due to unacceptable residual deformations, remains unavoidable, which can lead to heavy economic costs and sometimes even financial disaster or social unrest. To minimize economic losses, structural resilience has become an important research area. The concept involves designing a structure that can recover quickly from a disaster without disrupting operations. Typical resilience techniques include the use of rocking structures, self-centering techniques, and post-e...
