Abstract

The invention relates to the technical field of building energy dissipation, in particular to an anti-failure energy dissipation extension arm with an additional amplification device. The anti-failure energy dissipation extension arm comprises a core tube, an outer frame column and an outrigger truss, the core tube is connected with the outer frame column through the outrigger truss; the outrigger truss is provided with an upper chord member, a lower chord member, diagonal web members and a rhombic amplifying device; the rhombic amplifying device is arranged between the upper chord member and a diagonal web member; the amplifying end on one side of the rhombic amplifying device is connected with the lower chord member through a damper; and the amplification end on the other side of the rhombic amplification device is connected with the lower chord member through the damper. According to the anti-failure energy dissipation extension arm with the additional amplification device, energy dissipation is amplified through the rhombic amplifying device, the working efficiency of the damper is effectively improved, under the small external force effect, the deformation amount and the deformation speed are amplified through the mechanical effect to excite the effect of the damper, a large amount of external input energy is consumed, the damage effect of external input on a main body structure is reduced, and the structural comfort and the anti-seismic safety performance are improved; and the anti-failure energy dissipation extension arm with the additional amplification device has important practical significance on the development of a super high-rise structure.

Description

technical field [0001] The technical field of building energy dissipation of the present invention relates in particular to an energy dissipation outrigger of an additional anti-failure amplification device. Background technique [0002] Earthquake action and wind load action are the two most prominent factors in the design of super high-rise buildings. Under the action of earthquake and wind force, structural deformation and wind-resistant comfort should not exceed the limit specified in the code, which is the focus and difficulty of high-rise design. Most super high-rise structures use the outer frame column and the middle core tube structure system. Outrigger trusses are arranged at a certain floor height between the outer frame column and the inner core tube. When the structure is subjected to horizontal loads, the core is adjusted through the coordination of the outrigger truss One side of the peripheral frame column is under compression and the other side is under ten...

AI Technical Summary

Problems solved by technology

The damper needs a certain amount of deformation or deformation speed to fully exert its energy dissipation effect. For some structures with small lateral deformation or structures under the action of small and medium earthquakes, it is difficult for the damper to fully exert its working performance, and its application is greatly restricted. Solving the above problems requires technical improvement of the existing outrigger trusses
