Problems solved by technology

[0003] Under strong earthquakes, the current outrigger truss is damaged due to the large shear force. Most of the damage of the outrigger truss is the compression yield of the diagonal members of the outrigger truss. This kind of damage is difficult to repair after the earthquake. , causing serious economic losses

Abstract

The invention discloses a replaceable outrigger truss system after an earthquake, which includes a core tube, a frame column and an outrigger truss. The outrigger truss is arranged between the core tube and the frame columns. The outrigger truss includes an energy dissipation beam section, an upper chord, a lower chord and a web. The lower chord is arranged parallel to the lower part of the upper chord. The web is arranged obliquely between the upper chord and the lower chord. The web is divided into a first end and a second end, the extension direction of the first end of the web intersects, and the second end of the web is connected with the core tube or the frame column. Both ends of the energy-dissipating beam section are respectively connected to the first end of the web. The core tube is arranged in the middle of the building. The frame column is arranged on the periphery of the building. According to the outrigger truss system that can be replaced after the earthquake in the embodiment of the present invention, the energy-dissipating beam section can consume the energy of the earthquake and play a role in protecting the web, and the energy-dissipating beam section is easy to replace after the earthquake, reducing the economic losses after the earthquake.

Description

technical field [0001] The invention belongs to the field of civil engineering, in particular to a replaceable outrigger truss system after an earthquake. Background technique [0002] With the development of the economy, the construction of a large number of super high-rise buildings has become the main trend of urban construction. Most super high-rise buildings adopt a structure that combines the middle core tube and the peripheral frame columns, and coordinates the stress and deformation between the core tube and frame columns by setting outrigger trusses. [0003] Under strong earthquakes, the current outrigger truss is damaged due to the large shear force. Most of the damage of the outrigger truss is the compression yield of the diagonal members of the outrigger truss. This kind of damage is difficult to repair after the earthquake. , causing serious economic losses. Contents of the invention [0004] The present invention aims to solve at least one of the technical...
