Eccentric supporting and energy-dissipating beam structure

Abstract

The invention discloses an eccentric supporting and energy-dissipating beam structure, and relates to the technical field of steel frame supporting structures. The beam structure comprises: a non-energy-dissipating beam, an energy-dissipating beam, a supporting beam, two frame columns, and auxiliary beams. The energy-dissipating beam is perpendicular to the length direction of the non-energy-dissipating beam, and the upper end of the energy-dissipating beam is connected to the bottom surface of the non-energy-dissipating beam. The two frame columns are respectively connected to both ends of the non-energy-dissipating beam. The supporting beam connects the energy-dissipating beam to one of the frame columns. One end of each auxiliary beam is connected to the supporting beam, and the other end is connected to the non-energy-dissipating beam and / or the frame column connected to the supporting beam. According to the beam structure provided in embodiments, flexibility of the beam structureis increased through reducing the number of the supporting beam, thus allowing other operations to be performed smoothly. Stability of the beam structure is increased through increasing the auxiliarybeams. Accordingly, under the premise of effectively dissipating seismic energy, the application range of the eccentric supporting and energy-dissipating beam structure is expanded, and the eccentricsupporting and energy-dissipating beam structure has good economic and technical benefit.

Description

technical field [0001] The invention relates to the technical field of steel frame support structures, in particular to an eccentrically supported energy-dissipating beam structure. Background technique [0002] Eccentrically supported energy-dissipating beam structure is a structural system with strong energy-dissipating capacity. Setting eccentrically supported energy-dissipating beam structure in a steel structure building can enhance the seismic performance of the building. During an earthquake, the eccentrically supported energy-dissipating beam structure can undergo local plastic deformation to dissipate earthquake energy and avoid building collapse. It is one of the indispensable structures for maintaining building safety. [0003] An eccentrically supported energy-dissipating beam structure is provided in the related art, such as figure 1 As shown, the eccentrically supported energy-dissipating beam structure includes: a non-energy-dissipating beam 1 , an energy-dis...

AI Technical Summary

Problems solved by technology

[0005] For the eccentric support provided in the related art, no matter where the energy-dissipating beam 2 is arranged, there must be a support beam 3 located in the middle area of ​​the overall eccentric support, so that the eccentric support has the defect of inflexible structural arrangement

At this time, the use of eccentric support in related technologies will easily affect other operations, such as process pipeline erection, personnel maintenance and other operations.

For example, when the process pipeline is arranged under the eccentric support, since the support beam 3 is located in the middle area of ​​the eccentric support, it will hinder the smooth passage of the process pipeline, so the pipeline must be set around the support beam 3, thereby increasing the pipeline Erection difficulty
