Anti-twisting novel soft steel energy dissipation device of plane irregular structure

Abstract

An anti-twisting novel soft steel energy dissipation device of a plane irregular structure comprises a locating connector 1, a first energy dissipation soft steel strip set 2, a second energy dissipation soft steel strip set 3, a first bolt hole set 4 and a second bolt hole set 5. Installation positions of soft steel energy dissipation strips can be accurately fixed through the arrangement of the locating connector. The soft steel energy dissipation device can not only improve rigidity of a building structure and improve structural damping, but also have effects of deformation and energy dissipation when the structure encounters an earthquake action and improve an earthquake resistant property of the structure, and meanwhile the soft steel energy dissipation device has functions of corrosion resistance and rust resistance, an installable/detachable function and other functions. The anti-twisting novel soft steel energy dissipation device of the plane irregular structure can be applied to not only a new-built structure, but also a reinforced improvement of an old building, and satisfies double needs of a newly-built building and an old building. With increasing complexity of a building structure form and increasingly improved requirements of people for building performance, the anti-twisting novel soft steel energy dissipation device of the plane irregular structure has a wide development space and wide engineering application prospect.

Description

technical field [0001] The invention relates to a novel torsion-resistant mild steel energy-consuming device with an irregular plane structure, which is especially suitable for improving the seismic performance of a large complex irregular plane structure. In earthquake-prone areas, when the large complex plane irregular frame structure is subjected to earthquake loads, the two horizontally intersecting beams are prone to relative rotation. This device can prevent their relative rotation and achieve energy consumption through self-deformation. Purpose. Background technique [0002] Earthquakes occur frequently around the world, accompanied by secondary disasters such as fires, floods, toxic material leakage, and epidemics. These earthquake disasters have had a huge impact on human life and seriously threaten the safety of people's lives and property. Since the beginning of this century, hundreds of strong earthquakes have occurred, bringing huge disasters to people all over...

AI Technical Summary

Problems solved by technology

Horizontal torsion coupling is a spatial problem, which cannot be simply simplified to a plane problem. Whether it is experimental research or computational analysis, especially inelastic dynamic analysis, there are great difficulties. So far, the relevant research work is not very deep. , it is difficult to provide a reliable basis for structural design

At present, the domestic and foreign design regulations on structural torsion are mainly based on single component tests or shaking table model tests, and the regulations on the number of structural floors are more based on earthquake damage experience, lacking the basis for quantitative analysis
